A large framerate mismatch with Blur Reduction will look very microstuttery.
Fortunately BENQ's own Blur Reduction works at all refresh rates, so you can run strobing at 80Hz or 90Hz, for perfect-looking motion (if you're willing to use VSYNC ON, perhaps simultaneously combined with some lag-reducing frame capping tricks), as Blur Reduction looks excellent with framerate-refreshrate matched motion. Don't forget to eliminate your mouse microstutters
If you have a game that varies a lot in framerate, from 30fps through 144fps, and rarely stays consistent, you might want to consider GSYNC if you hate stutters. GSYNC allows a very good-looking varying framerate. (TestUFO simulation of GSYNC
-- smooth framerate changes).
