Overwatch and XL2720z HELP please!

Post by Salaverry » 10 Jul 2018, 16:32

Hello guys,

A couple of years ago i changed my old samsung 120hz monitor for this one, the zowie/benq XL2720z. I'm pretty happy with the size and everything, but i really don't know why i dont see overwatch smooth as it should be.

My current pc is a 8700k and a 1080ti, i run 300fps.. i've tried with 1 max pre-rendered frames, different videos settings, all things up to date, blur reduction on/off, different AMA, but still doesnt feel smooth.

I have to say that it feels better at 300fps, if i turn it to 270, 240, 144, or whatever other value it feels worse and if i activate the blur reduction is kinda the same but a little bit worse on my opinion.

I was reading some article of g-sync and it seems is not the solution, ofc i want the best input lag possible... but i've been lost since forever with this. May be the monitor? the game? some settings i'm missing or did i setup something wrong?

Honestly ANY help would be appreciated... Thanks!

do you use display port or hdmi ?

the best solution for getting the best smoothness
1. enable vsync from the nvidia control panel not from the game (less input lag) and keep every thing on default settings
2. you have to match your monitor hz. by capping the fps on 144 thru the game or try the RTSS rivatuner.

if you have a lower fps on other games its better to choose the closest hz to your game or the lowest fps possible to mach your hz

tearing mostly happens on some games if you dont enable vsync, and some games you well not notice tearing at all
i didnt played overwatch before, so i dont have an idea if this game have tearing or not with 144hz

stuttering: if your fps lower than the refresh rate you well get stuttering, thats why its better to run your monitor hz with the lowest fps possible with your game, if there is any fps drops less than 144 you well notice stuttering.

as you mentioned you run the game 300fps so i think your frame rate well never drops less than 144, so just try to enable the vsync from the nvidia control panel with capping your fps.

if you want less input lag you have to cap your game 1 or 2 frames less than your monitor hz. 143 or 142, but you well notice a little bit of stuttering

conclusion : 144hz = 144fps + vsync is the best smoothness if you dont have a VRR monitor

Without vsync it's not possible to get truly smooth motion. Insanely high FPS can produce smooth motion without vsync, but we're talking 500FPS+ here. At 300FPS the results are not terrible, but not very smooth either. That's just how it works, I'm afraid. There's a reason vsync exists.

VRR (FreeSync/G-Sync) does help in getting vsync smoothness without the input lag penalty. If you can use an AMD GPU, you might try and see if the XL2720z can be tweaked through CRU to enable freesync. I don't know if it actually works with the XL2720z though, but with some monitors it works:

Other than that, you might try the low-lag vsync "trick" as described here:

For OW, you'd need to disable the in-game frame limiter (or set it to a high value like 300) so that it doesn't interfere with RTSS. Note though that although this method does lower vsync lag, it's not as low as G-Sync/Freesync.

If you are thinking about getting a G-Sync monitor, we have extensive G-Sync input lag tests for OW:

The "TL;DR" of the g-sync tests is that when comparing the same frame rates (141FPS in-game cap in this instance) then G-Sync has the same input lag as vsync OFF.

Note that the g-sync input lag tests were also independently confirmed by Battle(non)sense:

In the latest beta, you don't need to. You configure fractional FPS limits in the UI.

Not trying to contradict anyone here but from my experience with the same setup - 2720z connected via DVI-D

- Fast Sync with 300 ingame cap worked well for smoothness. A good mix of not feeling laggy.

- Frame Cap to 142 in game with V-sync ON in Nvidia Control Panel. This visually looked the most smooth but your SIM suffers due to the lower frame cap.

The two prior modes would keep the game CPU bound.

- RTSS Cap 144.007. Looked visually the same to me but made the game GPU bound and I could not get used to it. I would then turn reduced buffering ON and it felt a bit better but I'd always end up on one of the other settings.

Really thanks man! The Vsync low input lag post helped me out, i didnt know about the RTSS... is it advisable to have the triple buffer on?

What are your thoughts on fast sync? I read somewhere else that with the double fps of your refresh rate would be pretty good too, but i want to hear your thoughts since you have so much knowledge.

BTW, and this may be personal opinion.. but is it advisable changing my monitor to a 240hz one to avoid any troubles?

Thanks a lot for the help guys!!
