Re: Acer 390Hz monitor - XV252QF
Yes, definitely. I have noticed my jumps from 144 Hz to 240 Hz to 390 Hz very easily. For me, the major selling point of this monitor is the insanely low overall latency it has. Everything feels instant, even coming from my 240 Hz TN monitor.Salemthecaz wrote: ↑07 Oct 2021, 08:28Thanks a lot! Is the jump from 165hz to 360hz significant? I was considering the Zowie xl2546k but TN has always been bad outside of competitive gaming

Re: Acer 390Hz monitor - XV252QF
I’m glad youre satisfied with your purchase. Would you say with all the features this monitor has including blacklight strobing, 390hz and low latency, it gives you a considerable advantage over the opponents, making getting the kills a lot easier?lizardpeter wrote: ↑07 Oct 2021, 15:56Yes, definitely.

Re: Acer 390Hz monitor - XV252QF
Coming from 240 Hz TN and playing a lot of games that cannot reach 390 Hz (only really Rocket League and CS GO get that high on my PC), I wouldn't say it gives an insane advantage, but I definitely think there is an advantage there that is worth it to me. I don't use the backlight strobing. However, the lower latency is very noticeable for me. I have only had it for a week, but in games like Modern Warfare 2019 and Battlefront 2, it feels as though I can instantly switch between targets and everything feels like it's connected right to my hand. I think I will need more time to adjust to the lower latency and to really get all of the benefits from this. Keep in mind, I was already using the Viper 8K, have an overclocked system, have all power saving features disabled, have fast RAM, have a ton of Windows tweaks applied, lock my CPU and GPU to max power states at all times, have all background services and performance lowering patches disabled, etc. So my system already had very low latency, which I think made it easier for me to notice when another X amount of milliseconds were removed just from this monitor alone. I would say that more than anything, a monitor like this raises the floor on your performance and slightly increases the ceiling. Everything does feel easier and more intuitive.Salemthecaz wrote: ↑07 Oct 2021, 17:00I’m glad youre satisfied with your purchase.

I should also mention that I'm not a noob, so people who are less in tune with their hardware and latency might not get as much benefit out of it as I have gotten. I used to play Fortnite on a pretty competitive level back when the game was good (earlier seasons). I'm also very highly ranked in all Call of Duty games (BO4, MW 2019, BOCW) with KD in the top 0.1% to 0.2% on the most recent title. I'm also one of the top players on Battlefront 2's Hero Showdown. I seem to get about the same reaction times on this monitor as my 240 Hz TN monitor, but maybe on average it is lower by a few milliseconds. I can easily and repeatedly get reaction times in the 120 ms range on Human Benchmark, a testing website, and that is with Windows DWM crap in the way too.

Re: Acer 390Hz monitor - XV252QF
Same setup with locked overclocks and power savings disabled. I can get some 140 shots with an average of ~150. Never saw anyone doing 120 before.lizardpeter wrote: ↑07 Oct 2021, 20:35Coming from 240 Hz TN and playing a lot of games that cannot reach 390 Hz (only really Rocket League and CS GO get that high on my PC), I wouldn't say it gives an insane advantage, but I definitely think there is an advantage there that is worth it to me.

Holy!!! Any links to a tutorial showing how to disable all the unnecessary stuff to maximize latency? And that’s some crazy numbers youre putting uplizardpeter wrote: ↑07 Oct 2021, 20:35Coming from 240 Hz TN and playing a lot of games that cannot reach 390 Hz (only really Rocket League and CS GO get that high on my PC), I wouldn't say it gives an insane advantage, but I definitely think there is an advantage there that is worth it to me.

Re: Acer 390Hz monitor - XV252QF
It's more like in the 120-130 range. It really depends on how much sleep I get and how I am feeling on that particular day. 127-128 is a really common number for me. Surprisingly, I was getting lower times with my Viper Mini than my Viper 8K, even though the Viper 8K is technically faster. I think it is because the Viper Mini's clicks were less stiff, shaving off a few milliseconds by requiring less force. I would also recommend trying out a program posted on this forum. It's like Human Benchmark but not browser based and can go full screen, bypassing DWM.

Re: Acer 390Hz monitor - XV252QF
I don't have any links to anything in specific at the moment. I might make a separate post of all of my tweaks if people are interested since it is kind of off topic for this post (even though this monitor is part of the puzzle). I will just list some of the main things. I cannot promise they will all make a difference. However, in combination I am absolutely sure that they lower overall system latency.Salemthecaz wrote: ↑07 Oct 2021, 22:49Holy!!!

Hardware:
Get the fastest hardware you can. Overclock it well, but not to the point of instability. This is very important for VRAM speed, as clocking that too high can result in the ECC kicking in so that you lose performance and don't even know anything is wrong. We don't like that error correction. Make sure you have fast RAM with XMP set or do your own overclocking. Manage temperatures well so clock speeds or things like the GPU aren't bouncing all around. I use custom liquid cooling and keep my GPU under 40 C. Having a super fast monitor (this one), mouse, keyboard, etc. also helps. I use 1600 DPI and 8K Hz polling rate.
BIOS:
Disable every power saving feature. Lock CPU clock speed and voltage. Disable C-STATES! Maybe update your BIOS if it's old.
Windows:
I am using WIndows 10 Pro. I disable HPET in device manager and leave it enabled in the BIOS. Use BCDEdit to set disabledynamictick to true. Enable the hidden Ultimate Performance power plan. Use EVGA Precision X1 or MSIAfterburner to lock the GPU clock speed to its maximum at all times. I use Game Mode off. Disable all Xbox crap and Game Bar. Enable Hardware Accelerated GPU Scheduling. Make sure enhance pointer precision is off and that Windows sensitivity is set to the middle one. Disable all background apps. Disable almost all startup programs. Disable fast boot. Go into the services and terminate any you don't need (Razer Synapse, for example) and set them to manual mode or disabled. Enable MSI mode for your GPU driver and possibly some other drivers. Change your network adapter settings (I can try to add what mine are later). Disable all devices/drivers you don't need (better yet, do it in the BIOS). If you are playing a game that is not DX12, disable full-screen optimizations. In NVIDIA Control Panel (change all of these settings globally) enable maximum performance mode, disable V-SYNC, disable all other SYNCS (G-SYNC, etc), and put low latency mode to on. Disable scaling and set it to the display. If the display is not an option or feels worse, use the GPU. I used it on GPU with my previous monitor. With this monitor, I use display. It shouldn't really matter unless you are running something at a non-native resolution. Use InSpectre to disable Spectre and Meltdown patches (if you're willing to) for a free 4-5% performance increase if you're on specific Intel CPUs.
I have some other things I will add to this when I edit it later (other BCDEdits, mouse buffer (not sure if this helps), and other things).

Re: Acer 390Hz monitor - XV252QF
Just going to throw some of my experiences with this monitor into this thread!
TLDR Lifechanging performance, big recommend.
Bought this monitor yesterday, and I had pretty low expectations in terms of "ingame performance", which were instantly shattered. For me, the step up from 240Hz to 390Hz felt larger than the step from 144Hz to 240Hz. The XV2 feels incredibly responsive, coming from the HP Omen X 25f, that i've used for a good few years. But I've only tested this in "Overwatch" which is an incredibly easy game to run at an average of 400 FPS. Can't say anything for games that run below that as I haven't played anything else on it yet.
However I had higher expectations about going from a TN to IPS panel, and I might just have gotten an exceedingly awful unit in my hands, but the viewing angles(I'm not even sure if this is the cause of what I'm seeing) are extremely poor? Possibly reflection handling also playing into this?
As an example, if i set my wallpaper to "Solid Color - White", when sitting an armslength away from my monitor, the middle of the screen is white, while the edges start shifting to blue after about 20cm off the center of the panel. It's worse in the lower left corner(backlight bleed?) than anywhere else, but overall the bottom of the monitor seems to be "cloudier" than the middle to top parts. I think I've heard claims that this can and will alleviate over time if I just keep the monitor running warm, so I'll give it some time before I decide to simply return it.
Another touted benefit of IPS over TN are "accurate colors" which, again, doesn't seem to be true for my particular panel. Atleast not in windows, in games it looks... fine? but in windows it's a complete mess for me. Edit: I found the sRGB mode, colors are ok now.
Also the OSD seems pretty glitchy. A lot of settings seem to be tied to some brightness presets, so changing a setting can suddenly shift the brightness, this has happened in more than a couple combinations for me.
Lastly my unit seemed to take an "overclock" to 398Hz using NVCP. However any changes to the EDID using ToastyX's "Custom Resolution Utility" seem to go completely ignored. And theres no mentions of 360Hz nor 390Hz i the EDID from what I can see? I can remove every single resolution and data block from the EDID with no changes to what windows seems to read.
Edit: Removed placebo.
