Any "G-Sync Compatible" vs "G-Sync" inputlag tests?

Talk about NVIDIA G-SYNC, a variable refresh rate (VRR) technology. G-SYNC eliminates stutters, tearing, and reduces input lag. List of G-SYNC Monitors.

Any "G-Sync Compatible" vs "G-Sync" inputlag tests?

Hiya

So I'm getting either Asus AQDM or AQN (240hz OLED vs 360hz IPS)

When I first found out about G-Sync -- I fell in love with it, got 180hz TN G-Sync Module panel for competitive and never regretted it.

I'm not pro anymore so I'm considering 240hz OLED. Actually despite the ULMB 2 and extra frames with AQN I really do wanna try OLED.
Still I want to perform at my highest while using G-Sync (with all the settings, reflex fps capped) and "G-Sync Compatible" inputlag or flickers people talk about would be a dealbreaker for me.

Is there any lag/delay tests on "G-Sync (Module)" vs "G-Sync Compatible"? Any info on OLED G-Sync? Any advices?

Each monitor usually has different levels of total processing and GtG performance "latency," separate of any G-SYNC native vs. G-SYNC Compatible differences, so to get a like-for-like comparison, you'd have to test two identical displays on the same system, just with one display having a module and the other not, and that's typically not the case; even if they have the same panel and are from the same manufacturer, monitor firmware between models and system drivers/driver implementation will still differ.

I.E. total latency is entirely relative. You can really only consistently compare a setup against itself where latency is concerned.

Anyway, there shouldn't be any discernible latency differences solely between G-SYNC native and compatible operation that I'm aware of, so it would be down to other factors.
