Actually Nightquaker, there is a somewhat ad-hoc solution to this driver switching dilemma until the issue is "resolved".

AMD's OpenGL driver is actually just one file, called atioglxx.dll and a GL profile file for games, called atiogl.xml. Both of them are located in the C:\Windows directory. (Just search for them using the search box).

What you can do, is the following:-

1. Switch to 11.11a drivers.

2. Grab the atioglxx.dll and atiogl.xml files from the system directory.

3. Back them up, and copy them into base of the ppsspp working folder together with your ppsspp executable file.

4. Now, switch back to whatever Legacy drivers you were using before this, which will restore performance in the aforementioned DirectX game titles.

5. Launch PPSSPP. The emulator will now use the 11.11a OpenGL driver file (atioglxx.dll) located in the ppsspp folder instead of your system's default OpenGL driver.

6. If you want PPSSPP to use your system's default (Legacy) OpehGL drivers again for PPSSPP for any reason, just rename the atioglxx.dll file or move it somewhere else.

I've done this with some success using the 32bit builds of PPSSPP. 64bit builds don't look for the .dll file in its own directory, so this solution doesn't work for them, unfortunately.

Good luck, and thanks for your time.
