I installed the 81.89 beta today and the picmip tweak seems to be no longer needed. There is no change in FPS now when applying after each map load. The people who experienced a boost with this new beta probably never used the tweak previously so didn't know. As far as the multiGpu tweak, I never got any significant boost with 81.87 and same with 81.89.

With the 81.89/81.94 drivers something has changed. When you first load a map, the picmip tweak isn't that needed. When i hit . to run it now, i gain maybe 1-2fps, that's all.

However, if you alt-tab out and back into game, fps drops by ~25% back to the level of previous drivers. Hitting . to run the picmip tweak restores performance again.

So in short, the picmip tweak doesn't really improve things a lot anymore, maybe 2-3%, but if you alt-tab out of COD2 at all, you will still need it.
