Should I turn off freesync and set od to extreme for the lowest latency? Can Vrb affect the delay (I can keep the 390+ fps stable, so it's more of a theoretical question, but I'm very interested)? Does anyone use it even at 390+ fps?
Yes, absolutely disable FreeSync and VRB for the lowest possible latency. I use it at 390 Hz. I'm not sure what you mean by "390+ FPS."

Disable FreeSync/GSYNC in the monitor's own menus and also in NVIDIA control panel. Disable VRB in the monitor's menu. Do not limit FPS to VRR range if you want the lowest latency (unless you are not using NVIDIA Reflex and are GPU bottlenecked, but that's a whole other story).

Thanks for your help. I'm very glad that you also responded because I saw that you are also a bit of a reaction time maniac.

By 390+ I mean that with such a high frame rate and frequency, many people do not see the point of VRB. Am I right that you are still using extrem overdrive? do you also use super sharpness?

Would you also like to know if you are using the contrast trick shown on the forum on this ips?

I'm using reflex, should I limit it in this case? In valorant, I noticed that if the fps is not limited, it indicates a network error.

thanks in advance!

I use extreme overdrive. The pixel response time of this monitor is simply too slow to keep up with the refresh rate, so every little decrease helps. I'm actually looking into swapping to the Zowie 360 Hz TN monitor or likely the upcoming Asus 500 Hz TN monitor as they will both have much faster response times.

I personally do not limit FPS. The reason one would want to limit FPS for latency purposes is almost solely because of the latency penalty that accompanies pushing a GPU to its limits. Battlenonsense has some very good videos showing this. Ideally you want to keep GPU usage under 90-95% as latency exponentially increases above that. It does continue to decrease as GPU usage decreases, but that is only at a given FPS. For example, you wouldn't want to decrease GPU usage to 50% by locking to something like 120 FPS when you were getting 200 FPS at 80% usage - the second case will have much lower latency due to more frames even though the GPU usage is higher. NVIDIA Reflex mostly eliminates the issue of GPU usage above 95% causing more latency and even helps at lower usage too. But ideally (for the lowest latency possible) you want Reflex set to ON + BOOSTED and to not cap frames but to also not have GPU usage be too high (by using something like an RTX 4090 at 1080p, for example). I just ordered a 13900K and will get an RTX 4090 next time the FE is in stock at Best Buy, likely to play at 1080p or maybe 1440p. I'm sure you know this, but I would also recommend using essentially the lowest settings possible for max FPS if you are GPU bottlenecked at all.

What is the IPS contrast trick you mentioned?
you can read about it on previous pages (95). They are used more for TN panels, I am copying here a previous answer from lizardpeter in this regard:

what is "the known contrast reduction trick" ?
Reduce contrast to help eliminate more problematic and slow transitions to extremes. I have the black boost on maximum which makes blacks a lighter color (also has a competitive advantage of being able to see in darker areas easier). Also reduce contrast on the monitor itself and compensate by increasing the brightness of the panel. I saw a noticeable improvement with these settings on my old TN panel. On this IPS one, I think there might be an improvement, but it’s less noticeable.

^ I tried these settings and I was getting bad hit registration in CS:GO, went back to my old settings and seen an improvement.

I have been capping at 500 on 5800x, 3070 csgo I can get 700-800-900 at times. What should the cap be? How can I monitor usage

8 8 10 all off ss very situational. as said previously since start

ps: it's not just reaction time that's been hammered. sharpness too. so you going high bright THEN ss is like creating a problem then justifying curbing it with something else that never needed to be there. it's kinda em.. you would know if you know that hdr400 is not really true hdr. i've finalized/realized this comparing night and day time visual quality on e8 peripheral(interesting name for a series).

needlessly higher lvl of brightness bleeds into other pixels is what i'm suspecting is going on. Pretty sure i've read something here or there relevant to those lines of thinking.

But I do not disclude the likelihood my eyes having been since way before pubg 2017 to at least benq 120hz tn debute year, more adept to absorbing more from the presented colors given, than yours would, you know, under the same "paler, but at least for sure safely far from over contrasted" paradigm.

too much colors is just bad. period. use a tn/tn like for 10 years and you will see, with eyes unclouded by candies, and why esport is still not irrelevant and what conversation we have here is frontier level stuff.
