ummm, installed Windows 8.1 x64 to test FPS and only problems so far.
First tried running LFS with max settings, and I get only black screen on start, obviously something related to resolution, but however same resolution work on Windows 7 using absolutely same drivers (same exe on AMD site for both 7 and 8). My standard cfg work, as well as min cfg.
Tried min cfg benchmark then, and it runs, runs, almost reaching finish line, press button to stop benchmarking and LFS crashes:

And when I tried put report in CODE tags by clicking button found out it does not work. Windows 8.1 + IE
umm neither smiles, umm nothing clickable
Looked up exports of DLL and this seems to be ReHook_CreateFileA(). In other words most likely FRAPS is causing LFS to crash.
Tried starting LFS "as administrator" and then crash does not happen :fp:

As nothing work on W8.1 and FPS is much lower I wouldn't recommoend anyone to switch (some wink smile or maybe facepalm)
and don't worry W8.1 is now on spare backup HDD, original HDD is untouched.
