Viewing Angles, Uniformity, Response and FreeSync
Curved VA monitors have no issues when viewed head-on or at a slight angle. But at 45° there is a definite shift to red and a 50% light falloff. Gamma doesn’t suffer too much, which means detail is still there. IPS retains its advantage here.
The story is the same when looking at the monitor from above; however, viewing it from this angle nearly wipes out screen detail. So don’t look down on your VA monitor. It just won’t look very good from that angle.

Our sample showed average screen uniformity. We didn’t see any obvious bleed or glow in the black field pattern, but the numbers show a little extra brightness down the center portion of the panel. At some angles it’s visible when the lights are out, but we there aren't any problems when playing games or watching movies. Color uniformity is technically perfect since the range of error values is comfortably below 3dE. We saw only even white tones from edge to edge.
Pixel Response & Input Lag

Gaming is the EX3501R’s forte, and that is supported by an excellent 11 milliseconds (ms) screen response and just 40ms of total input lag. The other monitors here are 60Hz screens, so that explains the victory.
There are faster curved ultra-wides out there, but at this price BenQ offers good performance. The most-skilled gamers will want something faster, but for the vast majority this panel has excellent motion processing and delivers a smooth, fast experience.
Gaming With FreeSync
Even though the EX3501R doesn’t have sufficient FreeSync range for LFC, it didn’t show much tearing at rates below 48fps. We were able to play Tomb Raider in the 40fps range with little problem. That was at the Ultimate detail setting, which is something of a drag for our Radeon R9 285. Turning down to High kept the action solidly over 60fps, which was much better for control response and smoothness. We tried both settings of the AMA controls and found little difference between High and Premium. No ghosting appeared when using the faster option. In either case, motion blur was minimal and almost non-existent at the highest framerates.
As a gaming monitor, the EX3501R will satisfy all but the most competitive players. 100Hz is more than enough speed for players of average skill. The picture quality alone is enough to recommend it. Contrast and color saturation are first-rate. Adding in the wraparound curve and large size just pushes it over the top. Sadly, we had no HDR games to try. Given our findings on the previous page, we’d say this monitor is a good but not stellar candidate for that format. We imagine by the time HDR titles are common, BenQ will have updated this model or released something better.

Uh ... Assassin's Creed: Origins, Final Fantasy VI?
I think you're confusing response time with input lag:
Response Time is a measure of how fast a pixel can turn on/off (yes I'm simplifying this...) and is what affects "motion blur". VAs are generally faster and better then IPS here and there are ways to fix a monitor with a slow response such as using ULMB.
Input Lag is the time it takes for a signal sent out by the source to be displayed on the screen, this has no effect on motion blur and IPS are generally faster than VA here. Example, click you mouse button and (40ms) later that action takes place on the screen, this is input lag.
If you're truely concerned about either of the above items, get a TN panel as it smokes both IPS and VA in both fields, but you will lose a lot of color, contrast, and viewing angle with a TN. I use to do competitive game and my main gaming monitor is still a TN; anytime I'm on a VA or IPS something just feels off and i suspect its the display speed. I didnt give up my CRT (NEC FP2141SB) as my main gaming monitor until 2012 if this says anything about it...
