For people who don't know, Fpse is the best playstation emulator for Android (and WinMo of course)
Fpse has just been updated with an openGL plugin, giving impressive graphics
But here is the fact: with an Adreno 205 (example! Xperia Play), the new openGL plugin is really fast
With mali 400, it has compatibility problems, some gfx glitches, but the working games are fast
BUT on the Sensation, as well as the Evo 3D, so our Qualcomm CPU + Adreno 220 combo, it's slow !!!!!!! (for me, and reported slow by every adreno 220 users on Fpse forum so far)
Example? => games in full 3D like Tekken 3 or time crisis are more than 50% slower on a Sensation than on a Galaxy S2, a Xperia Xplay, and every other device with Adreno 205
Time crisis is exactly 66% slower on my Sensation at 1.7 Ghz than on an Xplay
(in terms of Frames Per Second, displayed by Fpse)
Forget about Gameloft games, emulation is another field, much more ressources demanding, no need to comment to say you have Angry birds or GTA3 running smooth, it's totally different.
Trying some possibilities with Schtruck (Fpse developper), trying to change some memory allocation features with modified versions of the plugin, it was impossible to improve these poor results.
So how can it be explained??? How can a single core with Adreno 205 perform better than a dual core with Adreno 220? (remind: it's also twice faster with a mali400, faster with powerVR GPU, onlt Adreno 220 is slow!)
What differences are here between Adreno 205 drivers and Adreno 220 ones?
Any hint appreciated, since I now hate my Sensation
EDIT: if you have a Sensation or an Evo3D, and have Fpse latest version with openGL plugin, please try games like Tekken 3, Gran Turismo, or another full 3D game, not an RPG like Final Fantasy, without frameskip, and repport displayed FPS. If you can go above 60 fps for Tekken 3, tell me which ROM you're using!!
