Hello. I think I found a solution for people who are experiencing FPS lags in games, including RaceRoom, this worked for me very well in all the games what I am playing. Please try following: close all the applications Windows-Logo-Button+R -> type cmd open as administrator enter bcdedit /deletevalue useplatformclock confirm with enter and a message should appear with a confirmation restart your computer and open the application After testing: Restart your computer again and test if the problem has vanished. If there are any problems (with other programs or Windows), the opposite command is: bcdedit /set useplatformclock true I believe this should work for Windows 8.1/8 Users as well, but I am not sure for 100%, because I am using Windows 10. I hope that this little command will make you happier and your gaming will become much more smoother and stable. For my PC it made some serious magic. I can't explain how it works in words, but it works in fact! And that's more than enough! Best regards, Yevgeny.
