The problem is most noticable when the mech is moving, it's as if the blurring is being applied too much, stationary and things become clear again. I made these two screens (cropped from 5760 * 1080) and posted in another thread...
Stationary mech:

Moving:

And here is one i took just now running the same hardware, just one screen (1920 * 1080) moving at 82kph...

Notice especially the amount of blurring applied to the canopy framing between the cropped ultrawide images and the standard 1920 image.
Any other 3 screen users experience the same issue (or know a fix)?
Hardware is a GTX690 running at 6038 *1080 (bezel corrected) on beta 313.96 drivers, although it was the same on the 310.90s
If this is a bug (and i would certainly put forward the case that it is) then please consider this a report (or please direct me to the correct place to file it).
