So uh, figured I'd share this with you guys but I think I'm actually getting 433Hz checked using none other than https://www.testufo.com/frameskipping of course. Been running this since I got the monitor with no issues thus far.

Chief or others - Can you confirm this is really producing 433Hz "physical" refresh?

Now I just need an RTX 3090 to keep those minimum frame times as high as possible.
CPU/RAM are primarily responsible for minimum framerates (e.g. 0.1% frametimes), not the GPU, FYI. But if by "minimum frame times as high as possible" you mean you want slightly higher average/maximum FPS, go for it.

I want both for sure.

I agree that CPU/RAM bottleneck will be the main factor in the majority of the drops but at the same time in Apex Legends at least, I've noticed that certain areas/environments are clearly GPU bottlenecked (CPU usage remains relatively constant and "low / moderate" vs GPU usage spikes 90%+ even at low FPS cap).

Currently running 24/7:

8700k @ 5.03 GHz, 0 AVX offset
DDR4 @ 3216 MHz, 13-14-14-28-350 + other optimizations

Plan to upgrade rest of system as soon as something worthy is out after I get my RTX 3090.

I got 433Hz to display, but it's frameskipping. Can you post a photo if it's zero frameskipping?

Testing other undocumented refresh rates now using my usual overclocking tricks, standby.

Yeah, to clarify, I'm getting frameskipping at anything above 366Hz but just wanted clarification that displaying at 433Hz with frameskipping = ~360Hz in reality. Is that true?

Also, here's what I get at 366Hz:

Warning: Could be placebo without further testing :)

On a side note, with some quick "unscientific" tests by playing some games and dragging windows vertically up and down at various speeds, I perceive less motion blur even with the frameskipping at 433Hz vs default 360Hz.

Hence why I was asking if we're truly seeing a "physical" somewhat 433Hz (or at least significantly higher than 360Hz) refresh and not just a 433Hz setting with only ~360 or say ~370 Hz in reality.

In competitive games I'm willing to tolerate some frameskipping (minor stutter?) for decreased motion blur and faster scanout overall.

...or maybe the frameskipping has some sort of strobe-like effect improving motion clarity.

Hey guys,

What is your calibration report?

Did I possibly get a bad screen? I see report deltas of 0.5 and 0.7 in youtube reviews while mine is at 1.03...

Should I send it back?

Correct. 366Hz is what I am able to get without frameskipping. Anything above just simply frameskips.

For improved clarity above 360Hz, there are possible causes. For example, GtG pixel response may be affected, or that the non-frameskipped frames are actually refreshing in 1/433sec. I will need to use a 960fps high speed camera to determine the cause. But, rarely, it is sometimes possible for clarity to improve somewhat even with frameskipping, because of other changes that occur (like GtG times or scanout times). If so, latency could be slightly lower but much more jittery (due to frameskipping creating latency randomizations).

Yeah, seems it could be more complex.

When I run my PG258Q at 258Hz, the mouse cursor noticeably stutters but I perceive slightly improved motion clarity during gaming.

Whereas I don't notice any mouse cursor stutter on my PG259QN at 433Hz but I haven't really examined that in detail. Clearly, it's likely stuttering, just it's harder to notice at these higher frequencies.
