Just a report on the current situation. Running R426 with OpenGL, without dual core. Intro movie plays fluidly, with sound. Ingame is slower. The graphics are almost as bad as usual. No menus. No helmet, HUD or gun. No particles. Rendering of distant objects got fixed. Some sound works, but the first few seconds of music get repeated randomly. Invoking the scan visor briefly makes the graphics a bit better (Helmet, HUD, cobwebs and smoke show for a split second). Scanning doesn't work. Because of this it's impossible to progress beyond the first scan console. At least it's stable and doesn't crash.
