How Valve Made L4D2 Faster On Linux Than Windows

[bridgman]

If there was that possibility then where is a GCC target for Nvidia or AMD GPUs (for C++ I mean)?

Most of the GPU-related work is using the LLVM backend rather than the GCC backend, and both NVidia and AMD have released code for that (not sure if the NVidia code targets IL or ISA though; we released code for both and are working to get them upstream into the LLVM project).

I imagine there will be a GCC target at some point (we're already being asked for it) but so far LLVM has been the priority.
