A comprehensive list of games that are only problematic on AMD/ATI graphics cards

[LunaMoo]

This thread is kind of outdated and most of those issues were only happening on very old hardware back from the "ATI" times.

To sum it up - AMD gpu's vs ppsspp should be divided to two separate cases:
- very old gpu's(HD4000 series and older aka all pre dx11 gpu's) which always had very poor OGL drivers and lots of those are completely broken, users of those cherry picked driver called 11.11a as "best one", probably not bug-free either,
- new gpu's which also have(or had / wasn't checking for a while;p) buggy OGL drivers starting from "crimson" series(of the driver), I belive your Tekken problem is exactly that. Modern GPU's that are old enough to have earlier drivers have a very easy workaround of copying pre-crimson OGL driver dll's into ppsspp directory, you could just grab those files from this user post or find a pre-crimson driver for your gpu and use that:].

If your gpu is too new to have older drivers or too old to have any quality drivers to begin with;p, as long as you use windows you can always use D3D backends as AMD is just as good as Nvidia with those.
- d3d9 is kind of outdated and I would only recommend it on very old systems,
- d3d11 on the other hand is pretty great, in some cases much better than OGL, both with performance and quality, but it's also new and still has few issues in some games that doesn't happen on other backends as can be seen here.
