Just FYI, but I have difficulty reading on monitors. I tend to SKIP words which is a hassle.
IPS is better than TN. 4ms or below for response time is desired (which minimizes motion blur/ghosting but note that 4ms on 60Hz is more noticeable than 4ms on 144Hz so probably there's very SLIGHT on the former but I doubt you could see ANY ghosting at 4ms/144Hz). There are reasonably good TN panels, and of course you have to try to estimate the quality of the monitor by perhaps using NEWEGG as a guide (overall egg average and look at 1/5 and 2/5 comments to see if common issues like failing or backlight bleed)… AMAZON sucks as they still after YEARS mix up user reviews between similar items. Includes TV's, movies, and so on.
Possibly the best feature for you is to have the HIGH REFRESH of 144Hz.
Again, this means you really need to understand (as you should anyway) how the following work. Pros and Cons to each.
1) VSYNC ON
2) VSYNC OFF
3) Adaptive VSYNC
4) Adaptive VSYNC (Half Refresh)
The main issues for the above really are SCREEN TEARING (vsync off), LAG (VSYNC adds one or multiple buffers), and added Stutter (VSYNC ON if you can't maintain the FPS).
You can use NVInspector to cap the FPS. Is there a better tool? Maybe. Anyway, here's a couples examples that MAY be optimal at 144Hz:
1) Tomb Raider (slower game). Either:
a) Adaptive VSYNC Half Refresh (tweak to optimize for 72FPS but allow drops below), or
b) VSYNC OFF (tweak settings for approx 50FPS or so, possibly set FPS cap for more consistent response and minimize tearing)
Possibly 50FPS is ideal depending on the screen tearing. It's also a tradeoff as always between FPS and visual quality unless you can run the game at max settings.
2) Diablo III
a) VSYNC - if you can maintain 144FPS
b) VSYNC OFF - I'd cap in this case to minimize screen tearing... makes CURSOR less smooth but screen tearing less annoying
c) Adaptive VSYNC Half Refresh - no screen tearing since it is effectively 72FPS. It's slightly less laggy/sluggish than it would be on a 72Hz monitor with VSYNC ON but more sluggish than VSYNC OFF on a 72Hz monitor.
I hope I didn't confuse things more... I think if you get the basic idea that VSYNC eliminates screen tearing but adds lag (and can add stutter if you don't maintain the FPS) then the options make more sense.
When I played Assassin's Creed Brotherhood I kept getting major STUTTER with VSYNC ON. I might do a jump from a building or whatever then suddenly it wasn't smooth... so I turned off VSYNC and it went away but the screen tearing was really horrible.
Then NVidia announced Adaptive VSYNC and I tried that. Where I normally got the stuttering I just got a little screen tear but the time was SHORT so it was barely noticeable unlike the stutter that was somewhat game breaking.
In Max Payne 3 it auto locks to half the FPS with VSYNC ON... so if I was at 60FPS/60Hz but dropped to 59FPS or below then BAM, locked to 30FPS/60Hz and it's really much more sluggish which sucks... forced on Adaptive VSYNC and problem solved... I just adjusted the GAME SETTINGS so I stayed on 60FPS about 90% of the time or more which was a good tradeoff between visual quality being good and occasional screen tearing due to VSYNC being forced off below 60FPS.
