Crashes, No Sound, or Screen Glitches?
Random freezes, missing sound and display glitches usually trace back to one bad driver. Find and replace yours safely.Free scan · under a minutePC Slower Than It Used to Be?
A free scan shows the junk files, broken settings and background clutter dragging Windows down - then fixes them in one click.Free scan · Windows 10 & 11To make a PC game demo run more smoothly, establish a repeatable baseline, then change one graphics setting at a time and compare frame rate, stutter, image quality, and responsiveness. Start with free in-game options—especially resolution and demanding quality settings—rather than assuming a hardware upgrade or one preset will work for every demo.
How to check whether a settings change helped
Use the same repeatable section of the demo or its built-in benchmark for each comparison. Record the resolution, graphics preset, average FPS, and 1% low FPS before making changes. The 1% low averages the slowest one percent of frames and can reveal stutter that an average FPS figure hides. NVIDIA’s FrameView documentation describes these metrics, along with latency and hardware telemetry.
Compare configurations using more than a single number: look at average FPS, 1% lows or frame-time behavior, image quality in motion, responsiveness, and tearing or other display artifacts. A still image can make an upscaling mode or reduced setting look acceptable even when movement exposes blur or other visual changes.
Use monitoring to identify the likely constraint
An overlay can help distinguish a graphics-memory problem from a general performance issue. Steam’s performance monitor guidance warns that performance is likely to suffer when a game’s video-memory use exceeds available memory. FrameView can also report GPU and CPU utilization and temperatures. Some of its latency readings require a supported game and may not appear in menus, so an unavailable reading is not by itself evidence of a problem.

Which graphics settings should you lower first?
Change one option at a time, replay the same section, and note the result. That makes it easier to tell which adjustment improved performance and what it cost in image quality. Steam Support says manually changing a game’s video options can increase FPS, but the result depends on the game and system; no setting guarantees a particular gain.
- Reduce resolution or resolution scale. This is a direct first test when frame rate is poor. Lower resolution can help older or integrated graphics, but it reduces image detail. Steam’s video troubleshooting guidance discusses reducing resolution as one possible way to improve FPS.
- Reduce demanding quality options. If the resolution change is not a good trade-off, test lower graphics-quality settings individually. Which options matter most varies by demo and hardware, so use measured results rather than assuming a universal order or FPS increase.
- Compare upscaling with native rendering. If the demo offers an upscaling option, compare it with native rendering in both a moving scene and a still view. The available sources do not establish one upscaler or mode as best across demos.
- Test the preset only after you understand individual changes. A preset can be a useful starting point, but compare it with your baseline using the same scene and measures. A higher average FPS is not automatically a better experience if lows, clarity in motion, or responsiveness worsen.
Should you turn VSync on or off?
VSync concerns synchronization between rendered frames and the display’s refresh behavior. Steam explains that frames beyond the refresh rate are associated with VSync and warns that disabling it can cause tearing or artifacts. AMD notes that in DirectX and Vulkan games, VSync is controlled in the game’s graphics settings.

- 5-in-1 Connectivity: Equipped with a 4K HDMI port, a 5 Gbps USB-C data port, two 5 Gbps USB-A ports, and a USB C 100W PD-IN port. Note: The USB C 100W PD-IN port supports only charging and does not support data transfer devices such as headphones or speakers.
- Powerful Pass-Through Charging: Supports up to 85W pass-through charging so you can power up your laptop while you use the hub. Note: Pass-through charging requires a charger (not included). Note: To achieve full power for iPad, we recommend using a 45W wall charger.
- Transfer Files in Seconds: Move files to and from your laptop at speeds of up to 5 Gbps via the USB-C and USB-A data ports. Note: The USB C 5Gbps Data port does not support video output.
- HD Display: Connect to the HDMI port to stream or mirror content to an external monitor in resolutions of up to 4K@30Hz. Note: The USB-C ports do not support video output.
- What You Get: Anker 332 USB-C Hub (5-in-1), welcome guide, our worry-free 18-month warranty, and friendly customer service.
Test the setting in the demo with your own display. Keeping it enabled may suit someone who prioritizes tear-free output; disabling it may suit someone who prioritizes frame rate or responsiveness and accepts possible tearing. Compare the same scene for both options instead of treating either choice as universally correct.
When should you use graphics-driver controls?
Begin with the game’s own settings. If you try driver controls, change one at a time and restore defaults if performance or image quality gets worse. AMD’s Radeon settings support article describes application profiles, shader cache, filtering controls, and Frame Rate Target Control (FRTC).

AMD says FRTC can reduce GPU power use, heat, and fan noise when a game renders far more frames than the display needs. It applies only to supported hardware and API cases, and changes require restarting the application. These controls are vendor-specific; do not assume an AMD option or its behavior applies to every graphics card or demo. AMD also notes that finding a balance between visual quality and performance can require multiple adjustments.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.When is a hardware upgrade worth considering?
Do not infer that a graphics card or cooling accessory is needed simply because a demo performs poorly. First check the game’s settings, official driver support information, and monitoring data. A GPU with more video memory is a conditional option only when monitoring and the game’s requirements indicate video-memory pressure.

- If monitoring instead points to CPU limits, a software bug, shader compilation, background processes, or poor demo optimization, a graphics-card purchase may not address the cause.
- If a setting change makes performance worse or introduces unwanted artifacts, revert it and compare against your recorded baseline.
There is no universal FPS-improvement figure for optimizing PC game demos. Results depend on the demo, hardware, driver, and display; use a repeatable comparison rather than relying on a promised percentage.
