New AMD/ATI drivers bug identified: workaround in r2015

[andutrache]

okay i tried to play P3P with the same settings i always used (GE to texture enabled only) and was stunned by the fact that it crawled at 10 fps, so i have done some testing and found out that:

With the 11.10, 11.11(a,b,c):
- if Vertex Cache is NOT enabled the game(P3P in this case) will crawl at 10 fps, with it enabled it never gets past 40 fps
- with shaders enabled and vertex cache enabled (+ or - VAO) it goes 60 fps constant but characters look like hedgehogs(in other games this setting seems to net the best results)

With the 11.5 and 11.9(possibly others):
- with only GE to Texture enabled i get 60 fps (with occasional dips to 40 fps)
- if you want to use shaders anywhere you will die trying.

Conclusion: Install the 11.11c driver(newest at the moment) and 11.5 or 11.9 driver.
Use 11.11c for games that need shaders to work (i.e Wild Arms XF etc...).
Use 11.5 or 11.9 for the games that do not need shaders to work.

The test was done using Jpcsp-x86 r2934 on Windows 7 x64.

I hate AMD !!!!!!!!!!!!

P.S: I have not tested the x64 version of Jpcsp because it stutters/lags like hell.
P.S.S: Oh and before i forget : I HATE AMD !!!!!!!!!!!!!
