--- Comment #106 from Alexey Loukianov mooroon2@mail.ru 2011-09-11 17:14:02 CDT --- Here is a lazy reminder to keep this bug "active": texture redownload for sRGB<=>linear conversion still happen with orm=backbuffer as of Wine 1.3.28.
GL_EXT_texture_sRGB_decode driver support still sucks: http://feedback.wildfiregames.com/report/opengl/feature/GL_EXT_texture_sRGB_...
What's interesting is that nVIDIA officially mentions this extension in FXAA PDF brief when it comes to porting FXAA to the OpenGL from DX10/11. FXAA brief I'm talking about was published towards the end of 2010. Now we're approaching the end of 2011 and this extension is not supported by nVIDIA OpenGL ICD neither on Windows nor on Linux.
Besides I don't get noticeable FPS drop in HL2:EP1 caused by this re-downloads when playing with orm=backbuffer (it looks like that with orm=fbo no re-downloads happen). It might be caused by recent changes in Wine 1.3.27 made orm=backbuffer several times slower in general comparing to earlier versions. This general slowdown might "mask" the slowdown caused by sRGB redownloads/conversions.
