* hmmm.. maybe they did some graphic improvements in the past 3 years? what do you think?


* i have my old buddy Adreno 203, which i used for about a year playing different psp games, and doesn't seem to show graphic errors, (i haven't tried racing games)
* thus, Adreno seem to have problems with speed


* i don't have mali device now, don't know if it's a better option


* @[Unknown] Disable Alpha Test is an Ultimate speed booster for adreno, don't know why.
* bad thing is it transforms some things into Square-shaped objects
* will it do the same for powervr?

->Disable Alpha test is purposely for PowerVR devices, but since some alpha tests are disabled in PowerVR on default, it wasn't much of a use now (5-10%fps increase) Still good fps with it unchecked. Just a Miracle-cure for some glitches (Persona3, 3rdBirthday, etc)

I have a 1Ghz dual-core Device with PowerVR SGX540 GPU, And I can Play MosterHunter3rdHD @100% with 1-2frameskip, "disable alpha test unchecked" [yes, it makes annoying glitches when checked(2d objects that supposed to have a transparent parts will show as opaque) alpha channels)

PowerVR->more Glitches, but Faster Than ADRENO
Adreno ->Some said it's slow due to incompatibility with PPSSPP.
Rumor said that SamsungGalaxyS2 perform better than higher specs devices due to its GPU... Don't know if it's true.
