I have both the htc sensation and the sgs2.although technically the adreno220 should be faster than the mali 400, most games,benchmarks,and even simple ui tasks do not reflect that it is. Both my phones are running cm7 and both oc to 1.6ghz. I can understand that the sensation has a higher res screen which demands more out of the gpu,but that does not justify the much too poor results that I get in games and benchmarks,specifically gl benchmark 2.1 using egypt high test. It runs very smoothly on my sgs2 at 57 fps while it runs poor on my sensation at 18fps.surely the extra pixels are not responsible for decreasing the performance that much. Note that this sluggish performance is reflected in the ui like switching between homes screens,app drawer ect... smooth on the sgs2, not so smooth on the sensation. I would like to get good performance out of the adreno 220 and overclocking and running a custom rom didn't help. Bad drivers from htc causing this? Any info on the matter would be appreciated.
im guessing its because you are running cm7... cm7 on the sensation is based off the AOSP and still in alpha IIRC... the roms on the sgs2 are supposed to be much more mature ATM
