--- Comment #17 from Stefan Dösinger stefan@codeweavers.com --- Fyi, I am in contact with Nvidia about problems regarding the floating point special behavior. They are aware of the issue and debating potential solutions, but I don't know if or when we'll see a fixed driver.
I don't want to work around this in our GLSL code. If we write generic workarounds for the different bugs experienced by one game each we'll end up with terribly slow shader code. As long as using the ARB backend works (and I'm keeping an eye on ARB regressions) disabling GLSL is my suggested workaround for affected users.
