NVIDIA G-Sync Pulsar monitor - Asus ROG Strix XG27AQNGV

Ask about motion blur reduction in gaming monitors. Includes ULMB (Ultra Low Motion Blur), NVIDIA LightBoost, ASUS ELMB, BenQ/Zowie DyAc, ToastyX, black frame insertion (BFI), and now framerate-based motion blur reduction (framegen / LSS / etc).

Whats the best settings to use for Counter Strike 2, when it boots up the game it asks you to put it into Gsync + Vsync + Reflex, but this mode doesnt look smooth to me and the frame rate is moving around alot.

On good hardware, capable of +400FPS, I wouldn't even consider using Pulsar.
Only ULMB2 with a good frame rate limiter or NV Fast-Sync, depending on which refresh rate one chooses.
Reflex is broken in that game, it's better to rely on external Reflex toggles (SK or RTSS after presentation)

Is Special K safe to use, doesn’t risk VAC ban?

I get over 400 frames so need to cap it.

Using Pulsar or ULMB2 at 360hz makes no difference to clarity, so might aswell stay in Pulsar.

Edit: actually I see your point, ULMB2 would get around the compensation pulse, I would have to test both.

Lol, if u have 700-1000 fps mb u will have a good prio over pulsar, but if u have 400 and u can use pulsar with 345-349 u will use pulsar, cause ~349fps and 400fps don't have any human eye diff, but pulsar have big diff in motion clarity

I know the Nvidia rep said they’re not going to lower the floor on Pulsar, but I seriously hope they reconsider expanding the ULMB2 range to 48 - 70 Hz for additional compatibility with retro consoles and PCs.

Anecdotally speaking, a acquaintance of mine used it fine on normal matchmaking. It's gray area :P
Don't use it for FaceIT though, that'll definitely prevent it :D

Precisely that :D
The raw frametime difference is also too good to give up on, as some hardware can push +500FPS with relative ease in CS2
You could also run 240Hz ULMB2 and use NVidia Fast-Sync, if you can maintain 480FPS.

Save your eyes and play games which won't need that range or rely on LSFG / Nvidia Smooth Motion.

That range is insufficient for normal VRR use.
≤324FPS @ 360Hz is the range you want.

@Kyube

The thing is, you can’t really apply frame gen on retro consoles or a Mister piped through a scaler unless you use a video capture card, at which point you can use literally any monitor instead.

Would be great if there was a singular modern monitor that works for all content. Nvidia can simply allow the customer to decide what is un/acceptable flicker, while even keeping the ULMB2 and Pulsar modes separate.

Cause? I'm use it and don't see any problem, use it even without vsync

So I ended up settling on Pulsar at 360Hz with Special K locking the game to 320 FPS.

RTSS doesn’t seem to lock the frame rate as consistently as Special K in this game. You can see the FPS fluctuating a lot more on the monitor OSD with RTSS, which affects smoothness and clarity. Special K feels much more stable.

I also tried fixed ULMB2 at 360Hz, but I wasn’t maintaining high enough frame rates consistently for it to stay smooth. When I dropped down to 240Hz ULMB2 it felt nice and clean, but I ended up going back to Pulsar at 360Hz with the 320 FPS cap. My lows don't seem to go lower than 320 that's why I settled on it.

This feels like the best balance for me right now. Unless I can somehow get lower than 5–7 ms latency, I think this is as good as it’s going to get.

Hey. Do you have a discord we can share to test some stuff together?

I found out that nvidia + reflex + gsync (vsync on "ON" in nvidia, not fast), capping my refreshrate at 360 in cs2 will cap my frames at around 327ish and make the smoothest in terms of gameplay + latency. Lvl 10 faceit.

I tested various things like gsync off, ulmb2 on, frame cap to 360, uncapped etc... and none of these tests made the game as smooth as pulsar+gsync+vsync+reflex.
