Create a Restore Point before tweaking to restore settings if conflicts arise.
1) Open Start Menu, type restore in the search bar.
2) Open Create restore point, select the Create button.
3) Name the restore point and click Ok

(These tweaks apply mainly to Windows 11, with some relevant for Windows 10.)

Adjusting display and graphics settings is crucial for optimizing game performance and visual quality on your monitor, ensuring proper use of the correct display driver.

So, how many Frames Per Second can the human eye see?

You may wonder what happens if you’re watching something with a really high FPS rate. Are you actually seeing all those frames that flash by? After all, your eye doesn’t move as fast as 30 motions per second.

The short answer is that you may not be able to consciously register those frames, but your eyes and brain may be aware of them.

For example, take the 60-frames-per-second rate that many have accepted as the uppermost limit.

Some research suggests that your brain might actually be able to identify images that you see for a much shorter period of time than experts thought.

For example, the authors of a 2014 study out of the Massachusetts Institute of Technology found that the brain can process an image that your eye sees for only 13 milliseconds — a very rapid processing speed.

That’s especially rapid when compared with the accepted 100 milliseconds that appears in earlier studies. Thirteen milliseconds translate into about 75 frames per second.

V-Sync, G-Sync and FreeSync

Adaptive-Sync was introduced by Nvidia as G-Sync. AMD also added FreeSync to provide Adaptive-Sync for their cards.

Enabling V-Sync could eliminate tearing, but causes increased lag and stutter.

The “Vertical Sync” (V-Sync) setting in Nvidia Control Panel set to “Fast” renders unconstrained almost as fast as V-Sync disabled, except doesn’t tear since frames rate above your monitor refresh rate will just drop the extra frames.

G-Sync can eliminate screen tearing and minimize the display stutter and input lag.

Leaving G-Sync on won’t cause any harm, running games beyond the maximum refresh rate of your monitor will disable G-Sync, meaning that if you’re playing an easier to run game there is likely no benefit to using it.

Display Settings

1) Open the Start Menu type Settings in the search bar. Open it and select System, then Display.

2) Choose the Display option and ensure you have selected the recommended display resolution from the drop-down menu.

3) Enable the HDR option too, if your monitor supports it, and also make sure Auto HDR is enabled.

4) Go back to the main Display settings page and choose Advanced Display.

5) Locate the Choose a refresh rate option and select the highest refresh rate from the drop-down menu.

Graphics Settings

1) Open the Start Menu type Settings in the search bar. Open it and select System, then Display.

2) Choose Graphics, and then select an app on the list, or search for the name of your game and click it.

3) Choose Options, and then click on High Performance, followed by Save.

4) Go back to the main Graphics settings page and choose Change default graphics settings.

5) Make sure the switch for Hardware-accelerated GPU scheduling is on

Flushing DirectX Shader Cache
On Windows 11, DirectX Shader is an optimization feature for storing pre-compiled versions of special instructions, known as shaders.
Shaders are small programs understood by the graphics card that control various graphical effects.
Compiling shaders can be time-consuming, and using a cache helps optimize performance by providing easier and faster access to pre-compiled versions.

The decision to clear the cache will depend on you. However, below are some reasons why you may want to do so.
To resolve performance issues – A cleared DirectX Shader cache may resolve some performance issues, including graphical glitches and stuttering.

Freeing up disk space – Even though the cache may not take up much space, clearing it will still free up some extra space on your computer.

To update the cache – If you have just updated your graphics card or installed new games, you may clear the DirectX Shader cache to fill it with new information.

Note: Clearing the cache is not something you must do often. It is mainly a troubleshooting step when you face some graphical issues.
This procedure will not negatively affect your system. This is because the cache is isolated storage with no permanent information.
You cannot disable or prevent the creation of the DirectX Shader Cache. Windows 11 has no official way of disabling this optimization feature.
Ccleaner provides an option to flush the DirectX Shader Cache.

To flush Shader Cache Using Disk Cleanup
1. Open Start Menu, type cleanup in the search bar, click Disk Cleanup to open it.
2. Select your C drive, then click the OK button.
3. Tick the DirectX Shader cache option and click OK.
Note: Though this is meant to flush DSC, it could be a good idea to check every listed item.
