Windows 7: Fixes for RtCW Single player and Quake II (OpenGL):

Fixes for RtCW Single player and Quake II (OpenGL):

Fixes for RtCW Single player and Quake II (default OpenGL mode):

Step 1 (for both games):
Download and install nHancer.

Step 2a (Quake 2):
Run nHancer and open Quake II profile while the game is not running. Go to Compatibility -> OpenGL, check "Conformant texture clamp" and set it to "Off", then check "Driver extesion limit" and type the value 11a8.

Step 2b (RtCW Singleplayer):
Run nHancer and open RtCW profile while the game is not running. Go to Compatibility -> OpenGL, check "Driver extesion limit" and type the value 4844.

Step 3 (for both games):
Enjoy playing these great games

P.S.: I found the fix for RtCW singleplayer here (post #7), and the one for Quake II here (post #2).

P.P.S.: I also had to remove zeckensack's Glide Wrapper in order to make RtCW work.

P.P.P.S: This can probably fix other OpenGL games too, try "11a8" for older games and "4844" for newer ones.

I have to wonder if RTCW issues are due to video card, people who upgraded from Vista to 7, or something else. I'm running X64 W7 on a new PC(fresh factory install) and the game runs fine. I'm not even using a superb vid card(standard Intel onboard).

This fix also works for SiN (the original, Quake2-engined one, not 'Episodes'). Either value will work.

This fix is only for nVidia cards. ATI cards don't need it.
(Tested with nVidia GeForce 9800 GT and ATI Radeon HD3470)

All games freeze in Single Player, plz help
Hello all, So I have a rather unique issue where Crysis, HL2:ep2 and COD:4 crash in single player mode, but never in multiplayer games. There is a pattern, however, which is that the games lock up during loading or saving points. I think it might have something to do with my permissions, but...
