That's very sad to hear as it effectively means that we'll be playing on Windows for the forseeable future since not everybody will have a Linux installation. But thank you, Feral, for trying!

Just out of curiosity: may we ask which compilers are you using on each platform?

And the short explanation above sounds somehow like one build is using compiler dependent fast math instead of IEEE fp computations. If this is the case, would it mean that the biggest problems could be solved by Relic by rebuilding the Windows build with standard fp and patching existing Windows installations?

Thanks again for trying hard and communicating it to the players!
