I don't know who else has this issue, but at some games it's like RTSS creates slight fps drops and stutter, if I disable it, the small stutters stop. I either try borderless full screen or full screen with Full Screen Optimizations to get correct frametimes, as well as RTSS, I always test the games to see which of these alternatives gives me smoothest experience. But at some games, RTSS it's not giving me optimal results and I can't understand why. Say I limit a game to 59.990 fps on a 59.995 Hz screen I will notice that the frames either drop to 58.9 or 59.something (59.8, 59.7, 59.6 fps) and then it will catch up again, despite the frametime always showing 16.6ms. The problem is that this happens way too often at some games forcing me to look for other alternatives to get better frame pacing. Please note that not all games have this problem, only some. A game that gave me this problem heavily was Middle Earth: Shadow Of War. Turning RTSS for that games does show that it "lags" the game sometimes, also happens at other games, some more and others less, others work perfectly fine. Do I have something in RTSS missconfigured?
