05/22/2020 UPDATE. The IPS 240hz monitor tier list.(I've measured/tried the all) and my honest explanation why.

[speancer]

In Europe we only have available the Acer predator xb273gx model and not the xb273x model, so by buying the gx version is there any compromise on motion clarity or response times?

Here is one in Germany https://www.proshop.de/Monitor/Acer-27- ... NC/2827621

Proshop is not a German store, just to clarify. They operate in Denmark and everything you buy comes from Denmark. If something is wrong with your purchase, you'd have to send a return to Denmark, so keep that in mind. I'd rather wait and get it from a local store.

Please after the purchase, post a feedback on the operation, I see many users complaining about the acer, which leaves me standing behind.

Thanks for the advice, one more thing not sure if you already mentioned this before but, i heard adaptivesync/ gsync/ freesync does give a tiny bit of input lag compared when its off.
2. is it best to leave it at 280hz no adaptivesync / no gsync and no elmb, if ur fps is fluatuating between 220fps - 280fps.if so is it best to leave it at OD 80 or OD 60 like you suggest, cause fps is fluatuating between 220hz - 280hz. not sure to cap it at 240hz or just leave it at 280hz since is able to reach that 280fps at certain parts in the game.
^ since OD 60 is best use for below 240fps and OD 80 best use for 265fps - 280fps above. if fps is always between 220fps- 280fps.
thanks in advance and stay safe

I don't notice any difference in terms of input lag with Adaptive sync ON vs OFF.

Since it's impossible for me to constantly output 280hz I simply set a 270/275fps cap with ELMB-Sync to get a flawless experience in the 220-280hz range.

OD60 is not bad at 280hz, however there's no point in using OD60 since OD80 has less overshoot at 280hz than at 240hz while slightly increasing motion clarity.
Stick to OD80.

What about the added delay with g-sync? i understand you can do elmb without g-sync? So in FPS games would you still use g-sync? Is this only to stop 90 percent of image tearing? I usto play with g-sync on my old monitor until i used a fixed refresh rate and it felt so much smoother.

Gsync itself adds no delay, the only benefit you get from turning it off is smaller frame-times which is good only if you can output 280+fps ALWAYS, I often use variable refresh rate since it's impossible to constantly play at 280hz, fps fluctuations look much more fluid with it.
If my fps fluctuates beetween 220 and 280 I simply cap at 275/270fps and I stick to Gsync, I don't like tearing since it makes aiming more difficult in fast-paced fps or during a teamfight where fps often drop substantially.
The only scenario where I play with a fixed refresh rate is if I play on this monitor at 240hz and I can output 240+fps 100% of the time.

Gsync easily stop 100% of the tearing.

Different monitors have different input lag with gsync, some have a lot of input lag and some others have virtually no delay (<0.4ms generally for this generation of 240hz IPS monitors, which is imperceptible).

Thank you, may i ask what games do you play? and what are your preferred settings or what settings do you leave it on, on your VG 259QM? HZ, OD, VRR on or off, ELMB on or off, Gsync/ Freesync on or off?
Thanks in advance and stay safe

Overwatch:
270fps limit + ELMB-Sync + Freesync + ingame Vsync.

Rainbow Six Siege:
235fps limit (config file)+ ELMB-Sync + Freesync + ingame Vsync.
(280hz is bugged ingame and it automatically reverts to 240hz, you can use the config file to set it to 280hz and force "Read Only" but it works 20% of the time)

Hyper Scape
270fps limit (config file)+ ELMB-Sync + Freesync + ingame Vsync.

League of Legends:
It isn't a game that massively benefits from strobing but it can make Moba's typical movement (like this https://www.testufo.com/framerates-versus) way smoother.
Gsync /Freesync is a must, tearing in Moba games is imo very noticeable and tearing when moving the camera is extremely annoying.
There's no fps limiter ingame so you need to change the config file (or use a 3rd party/driver fps limiter)
(config file)
235fps limit (config file)+ ELMB-Sync + Freesync + ingame Vsync.

I always use ingame vsync + capped fps since vsync helps with frame pacing(capped vsync has no input lag, ingame vsync is tied to the game engine so it's generally superior to driver vsync) + it helps with fps drops.

I want to talk about Warzone to give you a different example, my fps fluctuate between 160 and 250. ELMB-Sync and ELMB are good only in the 200-280hz range so I keep it disabled. I enable Freesync/Gsync with a 235fps cap to make the framerate fluctuations smoother and I set the overdrive to OD60 since it is more consistent than OD80 in the 144-230fps range.

why a 270 limit when the blurbusters guide says 3fps limit is perfectly safe for all games? Also on rainbow six, if you run boarderless you will run at your desktops refresh rate (280hertz) and thanks for the info and your setups, ill try your warzone setup.

Also, 5-to-8fps-below is probably sometimes needed for 280Hz-360Hz, due to ultrashort refreshtimes.

im confused.. i only play CSGO, VALORANT, League of Legends at a 300-400 fps Range. whats the best choice?

the XB273 or the VG279qm/VG259qm ? ( size doesnt matter to me ) also i dont need strobing or sync stuff. Just raw 400fps cs go 240-280 hz performance for the best possible input.

Thanks..

if your FPS is that high, i would get the highest refresh rate monitor that is readily available which means the 280hz asus monitors.

how much does your FPS fluctuate when actually playing those games? Because quite frankly, if the FPS is fluctuating between 300-400 then you should really consider setting a frame rate cap since the chances of seeing microstutters or missed inputs is extremely high if the FPS fluctuate too much; thus messing up your precision.

That or buy a stronger CPU , that way there should be less fluctuating FPS if you set the framerate cap to your desired amount.

or u could just wait for the 360hz monitors to come out in FIVE months. Me personally, that's way too long. (unless u don't mind losing a lot at competitive ranked matches)
