Optimal G-SYNC settings for a 500Hz monitor in CS2? G-SYNC/VSYNC/Reflex/FPS cap confusion

I recently upgraded to a 500Hz MSI MPG 271QR QD-OLED X50 (1440p 500Hz) and I'm trying to figure out the optimal settings specifically for CS2.

I used to play on an old 144Hz monitor without G-SYNC, so I've never really used VRR seriously.

I've seen a lot of conflicting information recently:

Setup A:

G-SYNC ON

NVCP V-SYNC ON

In-game V-SYNC OFF

Reflex ON / ON + Boost

fps_max 0

Let Reflex handle the FPS limit

Setup B:

G-SYNC OFF

V-SYNC OFF

Reflex ON

fps_max 0

Completely uncapped

Setup C:

G-SYNC ON

V-SYNC ON

Reflex ON

NVCP FPS cap slightly below refresh rate (around 439 FPS for 500Hz)

I've also seen people recommend NVCP Low Latency Mode = Ultra when Reflex isn't available, while others say Reflex replaces/overrides Low Latency Mode.

So I'm wondering:

For a 500Hz monitor specifically, what is currently the lowest-latency setup for CS2?

If I use G-SYNC, should I leave fps_max 0 and let Reflex cap automatically, or manually cap around 439–495 FPS?

Is an NVCP FPS cap preferable to the in-game fps_max limiter in CS2?

For a 500Hz OLED, should Response Time / Overdrive = Faster be used, or is there a better setting?

If anyone has tested these configurations with a 9800X3D + NVIDIA GPU + 500Hz display, I'd especially like to hear your results.

I'm mainly interested in measurable latency/frame-time differences, not just "it feels better."

Thanks!
