Performance issues:
1. Silent Hill 3 does not run well on laptops with an Nvidia GPU, it will run on integrated graphics. It is unknown if this is also an issue with AMD laptops:

The fix for this would be to use "d3d8to9" or "dgVoodoo" but these tools are not fully compatible with SH3 and causes grahpics and performance issues.

If you would like to use these tools regardless you can rename their d3d8.dll to d3d8R.dll.

Crashing/Hang issues:

3. It is recommended to use the cracked (No-DVD) sh3.exe as the original exe is protected with SecuROM and might cause issues with the mod.

4. Run SH3FileValidator.exe to make sure you don't have any missing or corrupt files.

Other:
1. The main menu is displayed in 4:3:

This is intentionally done to not stretch the menu as doing so can look quite poor.

2. Save files can not be created or loaded:

If the game is installed in the "Program Files (x86)" folder you will need to start the game with admin rights every time. It is therefore recommended to install the game elsewhere.

3. Anisotropic filtering doesn't work:

Anisotropic filtering is not available on AMD GPUs.

4. Icons are missing from the map/cursor is missing from puzzles:

This is caused by an unknown GPU driver.

If you are experiencing this issue please write a comment on the PCGamingWiki page with your CPU, GPU and Windows version.
