RPGM games run too fast

[jams666]

Some rpgm games I play run way too fast because my monitor is a high refresh one, but some games are perfectly fine, is there a way to get the fast ones to run normally?
Would prefer not to change my monitors hz every time I play one of the troublesome games.
thanks

Have also same problem, i try to play Slave Sword which seem to be very nice, but it seem that its hardcoded monitor (170hz) sync and its so anoying to play. i do not want to change monitor hz and it seem that even via nvidia panel i cannot desync it .
