There are no Xbox Series X emulator settings that can provide a supported, stable 45 FPS version of God of War III Remastered. The game is a PlayStation 4 release, while Xenia emulates Xbox 360 software on Windows PCs and is not an emulator runtime that you install on an Xbox Series X. RPCS3 targets the PlayStation 3 original, and its official compatibility entry lists God of War III as Ingame, not Playable. The only documented route with a selectable 45 FPS cap is the community Windows/Vulkan port known as gow3_pc, which requires a legally obtained PS4 dump and compatible PC hardware.
Why an Xbox Series X 45 FPS profile does not exist
The requested combination of console, game edition and emulator does not line up technically. God of War III Remastered is the PlayStation 4 remaster. Xbox Series X backward compatibility covers selected Xbox 360, original Xbox and Xbox One games; it is a curated compatibility system, not a general-purpose emulator installation environment. Xbox states that features such as FPS Boost and resolution improvements vary by title on its official backward-compatibility page. There is no supported Xbox listing or user-facing emulator package for this PlayStation game.
Xenia describes itself as “an open source research project for emulating Xbox 360 games on modern PCs” on its official site. That definition matters: Xenia is a PC application for Xbox 360 software, not an Xbox Series X application and not a PlayStation 4 emulator. Its FAQ also answers whether Xbox One or Series game dumping is supported with “No, and no,” and says that performance improvements come from a faster PC or future emulator optimizations rather than a magic settings profile (Xenia FAQ).
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Because the remaster is PS4 software, an Xbox 360 emulator cannot load it. Changing resolution, shader, cache or frame-pacing options in Xenia cannot turn the wrong platform into the PS4 remaster. A supposed “best Xenia settings” guide for this title is therefore solving a different problem or confusing the remaster with another edition.

gow3_pc |
PlayStation 4 God of War III Remastered | Community Windows port using original x86-64 code and Vulkan graphics translation | A 45 FPS cap is available in its launcher; a universal locked result is not promised | Closest documented PC alternative, requiring your own PS4 dump |
How the community PC port works
The current gow3_pc project says the original x86-64 game code runs directly on a PC CPU and that graphics are translated to Vulkan through shadPS4 technology. The project explicitly says “there is no emulator.” That makes it different from both Xenia and RPCS3: it is a native-style Windows executable path built around the PS4 release, not an Xbox 360 or PS3 emulation profile.
Tested game identifiers in the project documentation include CUSA01623 and CUSA01715, with versions 01.00 and 01.02. The launcher exposes a frame-rate limit from 30 FPS through unlimited, render-resolution controls, and 120 FPS and 240 FPS engine patches. Selecting 45 FPS is therefore possible on the PC port, but the documentation does not claim that every computer will hold a perfectly locked 45 FPS.
The project’s published test machine was a Ryzen 5 5600X with a Radeon RX 6700 XT and 32 GB of RAM. It averaged 144 FPS at 1080p, with a reported range of 55 to 240 FPS. That is one author’s result on one configuration, not a benchmark guarantee. The low end of the reported range also shows why an average above 45 FPS is not the same as a frame-time lock: a different scene, driver, shader compilation event or hardware configuration can still produce dips.

Requirements before attempting the PC route
- Windows 10 version 1903 or newer, 64-bit, or Windows 11 64-bit.
- A graphics processor with Vulkan 1.3 support and current graphics drivers.
- Your own dump of the PS4 game. The project does not include game files.
- A game build matching one of the identifiers and versions documented by the project, where applicable.
- Sufficient storage for the dump and working files, plus a controller or keyboard setup you can configure in Windows.
Ownership and dumping requirements vary by local law. The technical project documentation requires a dump from the user’s own PS4; downloading an undistributed game image is not a substitute for that requirement.
Step-by-step: selecting a 45 FPS cap on Windows
- Install a supported Windows environment. Use 64-bit Windows 10 (1903 or later) or Windows 11. Apply current GPU drivers before troubleshooting performance.
- Confirm Vulkan 1.3 support. The port’s requirement is Vulkan 1.3, not merely a graphics card that can launch older Vulkan applications. If your driver exposes an older Vulkan version, update the driver or use hardware that meets the requirement.
- Prepare your own PS4 dump. Do not expect the launcher to supply the game. Verify that the dump corresponds to a documented title ID such as CUSA01623 or CUSA01715 and, where possible, to version 01.00 or 01.02.
- Launch the port and choose the game. Point it at the legally obtained game data using the path controls supplied by the project. If the title is not detected, check the dump structure and title ID before changing performance settings.
- Set a conservative render resolution first. Begin at 1080p while establishing frame pacing. Raising resolution increases GPU work and can hide whether a 45 FPS problem is caused by rendering load or CPU-side emulation/translation overhead.
- Open the frame-rate limit control. Select 45 FPS rather than Unlimited. The documented launcher range is 30 FPS to Unlimited, so a 45 FPS cap is a valid selectable value on this PC port.
- Leave 120 FPS and 240 FPS patches disabled for a 45 FPS target. Those patches are intended for higher refresh-rate experiments. They do not improve a 45 FPS lock and add another variable when diagnosing timing.
- Play a repeatable scene for several minutes. Check for sustained frame time, not just the counter in a quiet area. A stable 45 FPS means consistent pacing at approximately 22.2 milliseconds per frame; a counter that briefly reaches 45 while hitching is not stable.
- Adjust one variable at a time. If the cap is missed, lower render resolution before changing several settings together. Record the result, then test another scene so you can distinguish a global limit from a location-specific hitch.
Understanding the 45 FPS cap and its limits
A cap tells the engine not to render above a target; it does not guarantee that the CPU and GPU can deliver every frame on time. The published 144 FPS average on the Ryzen 5 5600X/RX 6700 XT test machine indicates substantial headroom in that configuration, but the documented 55–240 FPS range demonstrates variability. It also does not describe frametime graphs, minimums across the whole campaign, shader-compilation behavior or results on Xbox hardware.
For a useful test, enable whatever in-game or overlay frame-time display your Windows setup provides, then compare several demanding encounters rather than relying on one menu or corridor. If the counter falls below 45 with long frame times, the system is performance-limited. If the counter remains near 45 but motion feels uneven, the problem may be synchronization, a display refresh mismatch or background activity rather than raw rendering speed.

When lowering resolution helps
Resolution changes primarily reduce GPU workload. They are the first practical adjustment when the graphics processor is saturated. Keep the 45 FPS cap in place while testing so that a faster uncapped result does not obscure whether frame delivery is consistent.
When lowering resolution does not help
If performance remains below 45 after a substantial resolution reduction, the bottleneck may be CPU-side code execution, shader compilation, driver behavior or a scene-specific limitation in the port. More GPU settings cannot fix an unsupported game dump, an outdated driver or a port compatibility problem. Capture the title ID, game version, Windows version, GPU driver version and a reproducible scene before seeking project-specific help.
Why RPCS3 is not a reliable remastered-game solution
RPCS3 is the relevant emulator when discussing the PlayStation 3 original, not the PS4 remaster. Its official compatibility entry for God of War III is marked Ingame, updated 2025-03-14, rather than Playable (RPCS3 compatibility list). “Ingame” means the title can progress into gameplay under the project’s classification; it does not establish a finished experience, consistent frame pacing or a stable 45 FPS profile.
Rank #4
- Versatile compatibility: supports Xbox Series X/S, Xbox One X/S consoles and PC Win10 and above (including the game platform Steam).
- Precise control: features Hall joysticks and Hall triggers for a comfortable feeling, long service life and improved game accuracy.
- Plug and Play Convenience: Wired USB connection (removable) for easy setup and instant play without the need for additional drivers.
- Customizable experience: Includes 2 custom backbuttons that allow users to eliminate false triggers and improve their gaming experience.
- Impressive gameplay: Provides a pulsating vibration trigger and an asymmetric vibration grip motor for intense tactile feedback.
Using RPCS3 would also change the game edition. You would be testing the PS3 original, with different assets and platform behavior, not God of War III Remastered for PS4. A PS3 emulator setting guide can be useful for that separate objective, but it cannot answer how to run the remaster at 45 FPS on an Xbox Series X.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What Xbox backward compatibility can and cannot do
Xbox Series X owners can use the console’s backward-compatibility catalog for supported Xbox 360, original Xbox and Xbox One games. The official page notes that the catalog is selective and that FPS Boost or resolution improvements vary by title (Xbox backward compatibility). The feature does not provide a sideloadable Xenia runtime, a PS4 compatibility layer or a settings screen where you can add an unlisted game.
Consequently, changing console video output to 120 Hz, enabling variable refresh rate or attaching a faster display cannot create a 45 FPS mode for a game that is not present in the supported catalog. Those display features can only present frames produced by a compatible game.
Decision guide: choose the path that matches your goal
| Your goal | Appropriate path | Reason |
|---|---|---|
| Play the PS4 remaster on a computer with a selectable 45 FPS cap | gow3_pc on supported Windows/Vulkan hardware |
It targets the PS4 release and exposes a 30-to-Unlimited frame-rate control |
| Run an Xbox 360 game on a Windows PC | Xenia | Xenia is designed for Xbox 360 emulation, not this PS4 title |
| Experiment with the PS3 original | RPCS3 | It targets PS3 software, but this title is officially Ingame rather than Playable |
| Play on Xbox Series X | Only titles in Microsoft’s supported backward-compatibility catalog | There is no supported user-installed emulator path for this remaster |
Troubleshooting the documented PC alternative
The launcher does not see the game
- Confirm that the dump came from your own PS4 and is complete.
- Check whether its title ID matches a documented identifier such as CUSA01623 or CUSA01715.
- Check the installed game version against the documented 01.00 and 01.02 versions.
- Recheck the folder selected in the launcher; changing the frame cap will not fix an invalid path.
Vulkan initialization fails
- Update the graphics driver from the GPU manufacturer’s current release.
- Verify that the adapter supports Vulkan 1.3.
- If a laptop has integrated and discrete GPUs, select the Vulkan-capable adapter in Windows graphics settings.
- Retry after closing overlays or capture software that may interfere with Vulkan initialization.
Performance is below 45 FPS
- Keep the 45 FPS cap enabled and test at 1080p.
- Monitor GPU utilization and frame time during a demanding scene.
- If the GPU is saturated, reduce render resolution.
- If the GPU is not saturated, test a different scene and update drivers; the limit may be CPU-side, shader-related or specific to the port.
- Do not enable the 120 FPS or 240 FPS patches while diagnosing a 45 FPS target.
The counter says 45 but motion stutters
Check frame-time consistency, display refresh configuration and background processes. A nominal 45 FPS counter can conceal uneven delivery. Test with a fixed display mode and no competing overlays, then compare the same scene again.
Bottom line for Xbox Series X owners
Do not spend time looking for Xenia settings for God of War III Remastered on Xbox Series X: Xenia targets Xbox 360 games on PCs, the remaster is a PS4 title, and Series X does not expose a supported user-installed emulator path for it. RPCS3 changes the target to the PS3 original and is officially only Ingame. If a 45 FPS cap is the requirement, the documented option is the community Windows/Vulkan port, using your own PS4 dump and hardware that meets its Windows and Vulkan 1.3 requirements. That port lets you select 45 FPS, but its documentation does not promise a universal lock on every PC.
