see my opengl post (see my signature for link). Specifically, see the chainfire3d section. on page 3 snakeblizkin mentions some issues which he used chainfire to ... help with. he has the same phone as you (it looks like). However, I've updated my chainfire3d section since then with Carlos25's experience. I don't have the chainfire3d app, but from these users' input you can probably get it working for you if you want to try to experience opengl. For me - I'm spoiled. I can't play without it now, even though it has slowdowns. The graphics are just too poor without it / too good with it.
I know we have a TON of options with openGL, but the truth is all our options (almost all) are just special fixes. The ACTUAL openGL options, the ones that control how well it performs and it's compatibility modes, schtruck has hard coded. they're the ones that you mainly spend time setting on the plugin on the PC. I think he has it set for max compatibilty, but I'm not sure.
