NVIDIA G-Sync Pulsar monitor - Asus ROG Strix XG27AQNGV

[mawi]

You're implying that GSYNC+VSYNC+Strobing+Reflex leads to a 2x latency increase.
Not only that, you're implying that RTSS cap (unspecified which one) is less total latency (in your particular game of choice) than the setup above, which is wrong.
Feel free to send the data from FrameView here, because I've not seen this reported anywhere.

No, you just keep interpreting things I dont say.

GSYNC+VSYNC+Strobing+Reflex is out of the picture. I dont know why you keep thinking I am comparing this to anything. It stutters like hell, I dont use it.

Reflex is OFF... OFFFFFF. Okay? It is turned OFF. O-F-F

In this case:

If you use Gsync on, Vsync on - you get pulsar clarity - higher latency (15ms)
If you use Gsync on, Vsync off, you dont get pulsar clarity - low latency (9ms)
If you use Gsync off... no pulsar clarity of course
If you use Gsync on, vsync off + manual framecap - low latency. But pulsar clarity is only there if you cap it with RTSS. CS internal and nvcp cap des not lead to pulsar clarity.

Take it, use it, or leave it. I am out.

Looks like TFT was very impressed. Biggest question they answered for me was the Pulsar latency penalty, which only ended up being 2.67ms when compared to 360hz without Pulsar enabled.

I've just noticed that, in TFTCentral's review, he claims that

Maximum Refresh Rate HDMI 360Hz
HDMI connection version 2.1
HDMI connection bandwidth 40 Gbps

Didn't someone here mention that HDMI is still limited to 144Hz?

This is the funniest part though
A separate 60Hz ULMB2 toggle


Oh, and for those waiting on <60Hz:

“No further change to the lower FPS limit for Pulsar planned
At one point there was mention of NVIDIA extending this lower limit down to 48fps via a future firmware update, but we’ve been told that the extra flicker during VRR Pulsar operation has made this unusable. Instead, and since the main interest in lower frame rate support was for enthusiast 60Hz ULMB operation, they’ve introduced a fixed refresh rate 60Hz mode for ULMB 2 instead as you can see in the new menu screenshot above. Pulsar will remain with a 75fps lower limit as it is now.”

& this part

Pulse width control
For ULMB 2 operation they’ve also added a strobe length control (via the ‘pulse width’ setting) although apparently it may not be introduced on all of the 4 initial Pulsar screens (confirmed present on Asus and Acer models). This isn’t available when using Pulsar, and we’re not sure if it would be practical to add a control for this as the pulse width and height is controlled dynamically during VRR situations to avoid brightness variation, and to account for the different frequency of the strobing. Those who like to adjust things for blur reduction modes will be pleased with the addition though for static ULMB 2 usage.

Does anyone have confirmation whether any of these monitors use DSC or not? I found I was unable to use DLDSR on the Acer monitor but I'm not sure if that's indicative of DSC being on or not.

My current settings are looking really nice on this monitor. I've done a lot of tweaks and testing with the suggestions in this thread. It seems that when my gameplay is capped at 319 then it's the smoothest motion and the lowest latency I've felt.

NVCP:
Low Latency - Ultra
Vsync- Fast

RTTS:
Capped at 342

In-game:
Vsync on (100%}
Reflex: On

You may have to "reset" Pulsar if you make changes on the fly. I do this by enabling and disabling sRGB mode in the game view menu (making sure that the OD setting changes, the screen will turn off and on). Try it out for yourself and report back with any new info!

Based on TFTCentral's review that the ASUS supports HDMI 2.1 FRL5, the display employs DSC on both HDMI & DP.
If it was FRL6, you'd be able to run without DSC through HDMi, which means you'd be able to use DLDSR

Acquired my second unit of this monitor.
I thought my initial unit was defective.
Like the PG27AQN before it, which I had 4 units of, I think this LCD panel suffers from poor brightness uniformity (a kind of vignette) that I am very sensitive too.

Other than that downer, I found the ULMB2 60Hz to be absolutely stunning for 60FPS locked games, emulators and such. ULMB2 60Hz also works with devices other than a PC -- Very impressed. Stellar work!

If Nvidia release this Pulsar/ULMB2 implementation on different panels, I will try my luck again and hope there's not this same brightness fall-off/vignette.

I am back to the XG2431 for now (but the future is bright!)

I think I can use DSR on mine, if this is what you mean:

The 60hz mode is stunning.

Interesting you mention a vignette, I didn't know this was a thing so I tested the brightness centre of the screen and it said 560 nits, and in the corners its 500 nits. When looking at the screen it looks uniform white to me but you must be seeing what the colour calibrator sees.

No more updates to pulsar going below 75 fps? are you kidding me? damn bro, the LEAST they could do is add a software profile toggle in nvidia control panel like they did for ULMB 1 to enable fixed refresh per game and then allow us to set the 60 hz mode on specific games we want to switch to ULMB 2. Nobody wants to sit there every day toggling between ULMB 2 60 hz and Gsync/pulsar using the monitor OSD, I would think they would move past this and allow at least DDC commands for us to toggle ULMB/pulsar using keyboard shortcuts or something. Really sad to see we won't see 60 hz pulsar They should at least work on improving pulsar at higher refreshes because right now it doesn't look as good as lower refreshes do.
