Windows 7 colours fuzzy in fullscreen game

It sounds like you have encountered a graphics issue while running Action Quake 2 on computers that cannot support the OpenGL renderer. The fuzzy colors you mentioned could be due to compatibility issues between the game and the software renderer on those systems. Here are a few suggestions to troubleshoot and potentially resolve the problem: 1. Update Graphics Drivers: - Ensure that the graphics drivers on the computers with the issue are up to date. Outdated drivers can often cause graphical glitches and performance issues. Visit the manufacturer's website for the latest drivers. 2. Compatibility Mode: - Try running Action Quake 2 in compatibility mode. Right-click on the game's executable, go to Properties, then the Compatibility tab, and check the box for "Run this program in compatibility mode for" and select an older Windows version. Apply the changes and try running the game again. 3. Graphics Settings within the Game: - Check if there are any in-game graphics settings that can be adjusted to enhance compatibility with the software renderer. Lowering graphics settings like resolution or disabling certain effects may help. 4. DirectX Installation: - Make sure that DirectX is properly installed on the computers facing issues. Action Quake 2 may rely on certain DirectX components for rendering. 5. Virtual Machine (VM): - Consider using a virtual machine on those computers with hardware limitations. A VM with proper graphics acceleration settings can sometimes improve the performance of games on older or less powerful hardware. 6. Compatibility Patches or Mods: - Look for any compatibility patches or mods available for Action Quake 2 that could address issues related to the software renderer on older systems. 7. Alternate Renderers: - Explore if there are other renderers available for Action Quake 2 that might work better with the hardware of the systems in question. Some third-party renderers may provide better compatibility. By trying these steps, you may be able to improve the gameplay experience for Action Quake 2 on the computers that cannot run the OpenGL renderer effectively.
