Hmm... I seem to be having a bit of a problem with my T5 stick. I use a PS2 adapter (of course) and test it, only 0.12ms of lag. Yet, in SFIV, for some reason, at times it seems to want to complete ignore me pressing the attack button while holding the stick in a direction. For example, with Bison's Jump HP, HP then Psycho crusher, it won't register the standing HP and instead I'll just end up going backwards. I jump then immediately hold back (and continue to), press HP then when I try to press HP while standing, it won't, instead I'll just start going back. If I hit HP again though while going back it'll work. It only happens sometimes too but it's making it impossible for me to do that combo.
Could it be the stick? adapter? what? I've never had any problems using it on my PS2 (duh) but on my PS3 with the adapter, it's a different story. Any suggestions guys?
