Who you gonna call? The Blur Busters! For Everything Better Than 60Hz™
https://forums.blurbusters.com/
I'm on my second playthrough of RE9. I updated to the latest Nvidia drivers thinking it might fix it but it didn't, so currently having to Frame Gen x4, I get 250 to 360 frames, its fine in that range.
Sad to hear... using x4 frame gen is actually the OLED solution for clarity... it should not be "ours".
I agree.
Does he mention the strobe on period behavior during Pulsar or ULMB2 use at different refresh rates in there? I don't have early access to the article.
Do you have an idea what exactly should have been tuned better for higher FPS ULMB2? As I understand it we can already tune the pulse height and width. Do you think it would've been good to give us an option to adjust the pulse shape as well?kyube wrote: ↑14 Mar 2026, 13:26That's what happens when you tune backlight strobing properly...

ULMB2 (@120, 240, 360Hz) should've been akin to ULMB2 60Hz in terms of perceivable eye-tracked motion clarity benefits.... but they completely botched it...
Much better, in fact, since higher refresh rate is easier on the eyes, the total eye-tracked clarity benefits are easier to achieve & brightness would be higher...
I strongly suggest that you avoid the 60Hz ULMB2 mode at all cost, it's extreme levels of eye discomfort.
Wait for Nvidia to fix their debacle...
You can probably tell from the Oscilloscope pics. Shows oscilloscope for ULMB2 at 360hz and 240hz. Then also for Pulse Widths 100, 50 and 10 for 360hz and 60hz ULMB2.
Establishing a direct communication channel for beta firmware testing would be mutually beneficial. If the firmware that runs on these monitors will be the same or similar to the ones on future Pulsar models, Nvidia has a clear incentive to gather early, direct feedback. This technology evidently requires significant tuning—whether from Nvidia’s engineering team or the end-user. At the very least, Nvidia should provide 'tinkering' options for various parameters, as motion blur perception is subjective and varies from user to user.brownvim wrote: ↑17 Mar 2026, 07:00I agree.
Would it be possible for NVIDIA to create a proper, dedicated feedback channel for Pulsar owners? Something like:
Right now it feels like the only way to get issues noticed is to post here and hope they get seen. A structured back-and-forth with actual engineers would help massively and probably speed up the whole process.
- A private beta testing program for early firmware builds
A direct feedback portal / Discord where we can report issues with logs/screenshots and actually get responses
Or even just an official monthly feedback thread that NVIDIA monitors
I (and I’m sure many others) are more than happy to help test and provide detailed feedback if there was an official way to do it.
I did not try this yet. But when Vsync is on (still talking about reflex OFF, not to confuse anyone), the higher latency is also there when your current frames are well within Gsync range. So i dont think using RTSS for example on top of vsync would lower the latency...Katzenwerfer_MX wrote: ↑16 Mar 2026, 20:18Are you sure this isn't because you are outside the G-Sync range and therefore falling back to regular V-Sync?
Could try combining G-Sync + V-Sync + any good limiter and see if you get similar results to the ideal setup you mentioned.
Kyube doesn’t actually own a Pulsar, so he hasn’t been able to test the new 60 Hz ULMB mode himself. Chief would probably be the best person to ask about this since he has hands-on experience with it.shapaco wrote: ↑17 Mar 2026, 08:38Do you have an idea what exactly should have been tuned better for higher FPS ULMB2?

Any chance we'll have a custom firmware in the future?

Chief doesn't own the one of the Pulsar QHD@360Hz models, as far as I know.
It's about hiding the total transition time.
Aw, I thought that he did a table of strobe on vs strobe off period, akin to his KTC M27P6 reviewbrownvim wrote: ↑17 Mar 2026, 08:55You can probably tell from the Oscilloscope pics. Shows oscilloscope for ULMB2 at 360hz and 240hz. Then also for Pulse Widths 100, 50 and 10 for 360hz and 60hz ULMB2.
Looks like Nvidias priority was to reduce flicker and brightness fluctuations in the Pulsar mode, that's why it feels so stable in brightness through the Pulsar range. Pulse width is dynamic in Pulsar mode, fixed in ULMB2 mode. Its far brighter than other competing strobing modes.
He mentioned the lower the brightness in 60hz mode the less you will see noticeable flicker.
