I know it has been mentioned in several topics, but I would like bring this to your attention. I have moved from an AMD 6950 graphics card to an nVidia GTX 970. My PC has a Core i7 @ 4.4 Ghz by the way. The new graphics card gives a nice FPS boost to GSCE, but strangely enough my FreeTrack lagged. Now I have set Max Framerate="-120" in my .PLR file and the problem is gone. Not only the FreeTrack lag has disappeared, but also the picture is smooth now. I think FreeTrack lags less because the GPU is not at 99% all the time and the CPU is waiting on the GPU. Limiting the frame rate gives the CPU more time to do something else. Or maybe it's a priority problem between GSCE and FreeTrack, don't know. Although my monitor is 60 Hz I have set Max Framerate to 120, since the FFB and physics are tied to the FPS (see this topic). As someone else said: "Having a higher FPS also can improve FFB response time, as well as increase user response time." Maybe this will help others too.
