Re: Starcraft unplayable on my nvidia - but works OK(ish) on Intel card
I wrote all this code and RenderTargetLockMode must be readtex. On GeforceFX (and other older Geforce) models we use GL_EXT_paletted_texture for 8bit rendering. There might have been regressions in this area which broke some stuff. Submit a bug report (bugs.winehq.org) and perform a regression test (read about that on wiki.winehq.org).
