Having issues like grey screen start up? Here's your fixes!
If anyone has issues launching doom 3 bfg edition here's how you fix the desktop crash issue. A) Radeon users you are required to update your legacy drivers for your graphics card, B) Nvidia users you have to turn off the AA or change it like with RAGE, and you have to update to the most current drivers, and C) Right click on the desktop or launch icon you use, and change the compatibility to xp service pack 2 as any others like sp3, sp1, vista, and so on will not work! Now, try it.
Here's some more fixes, and somethings I already said!
Possible Solution 1: Run the game as ‘Run as Administrator’ by right clicking. If you are using Steam then navigate to:
32bit – C:\Program Files\Steam\steamapps\common\doom3.exe
64bit – C:\Program Files (x86)\Steam\steamapps\common\doom3.exe
Right click on game.exe and select “Run as Administrator”.
"Will be the .exe with the pentagram icon"
Possible Solution 2: Run the game in compatibility with Windows XP SP2[only one that will work full on golden!].
Possible Solution 3: If game doesn’t launch, make sure you’re connected to the internet and try restarting Steam/your computer.
Possible Solution 4: Also, you can try to lower the game’s settings by disabling VSync and multi-sampling and turning down environment detail levels.
Possible Solution 5: Try to Update Your Graphics Cards and Motherboard Drivers
Possible Solution 6: Try different resolution options on your PC.
Possible Solution 7: For NVidia users, go into NVidia control panel and add your game.exe and make it "use NVidia GPU" to resolve this issue. And also try this, go to NVidia control panel and check if game.exe has to instances. If there are two instances, set both to use your specific GPU instead of automatic.
