POSTED UNDER SUGGESTION OF TECH-SUPPORT:
I am using PrecisionX16 (in its latest version) with a 980Ti (latest drivers) and noticed that with Star Citizen, the frame-rate indicator appears to be terribly inaccurate on my system.
 
I wondered why this might be. Specifically, I can be standing in one area without anything changing and at one moment the FPS displays as 19,18, 20, 21 (in that region) and then will sit at 60. Here is the kicker: IN APPLICATION, THERE APPEARS TO BE ABSOLUTELY NO DIFFERENCE IN FRAME RATE despite the display reading such an ENORMOUS change.
 
Fortunately it looks and feels like it is staying at 60 (Vsync is activated as this was on a 60 Hz display - otherwise I imagine the frame rate could be much much higher).
 
At any-rate, what I am wondering is this -- Why would the fps display be indicating 60-61 fps and then jump to the high teens and low 20s when nothing is changing, AND perhaps more significantly when there does not look or feel to be even the most minuscule decrease in performance whatsoever --- when it has supposedly dropped from 60 fps to 18 fps according to my PrecisionX 16 OSD?As a side: No other game seems to display this type of apparent strange behavior with the fps indicator on PrecisionX 16.

Haven't tried Afterburner (had previously heard of frame rate errors with Afterburner in other software) :-). I considered installing it and giving it a try but figured it wasn't a big enough concern to muck about too much. I just wondered what might be happening since it seemed so strange.
