I don't know, could be a hit or miss. But I've got similar problems with some games, and found out the issue was the new Nvidia drivers that cause some shader functions to return NaN instead of INF+ so could you try this patch which fixes these kind of problems in Source engine games.

Like Garry's Mod dxlevel 95
