Perhaps there are other changes from using the IEEE instruction variants, e.g. (There was some additional desire to expose that in a GL ext for WINE to use, but it got shot down pretty quickly.) I added a flag to be used by st/nine to enable the DX9 behavior optionally, but leave the IEEE behavior for GLSL. The main difference between IEEE and non-IEEE is whether 0 * infinity = 0 or NaN. > Looks like some numerical issue then, albeit I don't know if the game is at > This matches the behavior of most other drivers, including nouveau, ![]() > r600g: use ieee variants of multiplication instructions > I've actually got that game myself here.
