Can you explain what you mean with "HW:Legacy Flip"?
Read up on presentation models in Windows.

Also, why would I cap my FPS with VSync? This isn't a pulsar panel, so I'd loose the ELMB2, would I not?
Because tearing & improper frame pacing is a far bigger detriment in CS2.
Strobing is a large potential eye-strain concern, even at 500-600Hz.
Not to mention that most E-TN/Rapid-TN (that aren't the XL2586X or 86X+) suffer from (colloquially coined term)
red fringing

Most of the time, I already have more than 600 FPS, and this is at 4:3 1440p stretched. So I'm assuming with the 1080p stretched, I'll easily have 600 minimum in 99% of the situations.
A lower resolution doesn't necessarily result in lower present-to-present time (what you see on the vast majority of overlays) aka higher 'FPS'.
FPS is a deceiving metric to rely on for evaluating total system latency.

Another thing I'm curious about:
Asus ROG Strix XG248QSG Ace
this monitor is said to have "ELMB Sync" which is a "lower" form of ELMB with VRR enabled.
Isn't that just Pulsar without the name?? And yes, maybe it's more like 50% strobing, not sure, doesn't mention it. But since it would be 600Hz without the Overclock...that's still 1200Hz clarity or so, with VRR, right? Better than the Pulsar monitors for CS2!
G-SYNC Pulsar (VRR+Strobing) is a form of
rolling scan multi-strobe PWM. They're implemented on models with a QD-based WLED backlight.
ELMB-SYNC (VRR+Strobing) is a form of
global scan multi-strobe PWM. It's implemented on models which have a KSF/PFS-based WLED backlight.
Generally, when you have a higher vertical frequency (refresh rate) & backlight strobing is enabled, you
should achieve a lower MPRT target, as most models on the market rely on a fixed pulse width.
Pulsar is relatively better, at least when speaking of a VRR+Strobing scenario. The current models are very gimped though.
I don't know the exact pulse width that ASUS uses on their 610Hz model, but I know that it
hits ~960cd/m² based on this data
When it comes to fixed refresh rate strobing:
ULMB2 on the new Pulsar models would net you 0,69445ms MPRT (“effective ~1440Hz”) You also won't have any desynchronization issue due to frame rate < refresh rate scenario when strobing.
ELMB2 on the ASUS Rapid-TN model is likely ~0,5ms (“effective 1600–2000Hz”) You're more likely to have desynchronization issue due to not being able to sustain 600FPS at all times & experience red fringing due to the use of KSF/PFS.
Eye-strain is another factor, which won't be present on the standard sample & hold route.
It's why I personally find GSYNC+VSYNC+Reflex on 610Hz TN's a better option when playing games such as CS2 & Valorant.
I wouldn't do the same on +500Hz OLED.
