Partial myth.
VRR has very little lag penalty if your VRR range is bigger than framerate range.
The lag complaints of VRR is mainly because of framerate ranges bigger than VRR ranges. Like 300fps CS:GO on 240Hz VRR. But here, we're talking about 390 Hz.
When we're talking about this Acer 390 Hz monitor, your framerate ranges usually are inside the VRR range. The lag penalty virtually disappears. And G-SYNC becomes esports quality.
Do you prefer best absolute latency or lowest latency-variability? Sometimes those are diametrically opposing.SheerFinesse wrote: ↑01 Nov 2022, 16:26I want the best input delay and performance to give me the biggest advantage possible
Sometimes de-stuttering or de-blurring decreases human reaction time bigger than the approximate lag penalty (0.5/390sec = barely over 1ms lag penalty for either strobing technology or VRR technology).
Remember, the latency chain includes the HUMAN.... and the HUMAN has a reaction time latency that can be slowed down by extra display motion blur (fixed by strobing), or by extra stutters (fixed by VRR). Never make the mistake of forgetting about the HUMAN!
Especially in games without crosshairs -- Rocket League, DOTA2, etc. -- then eye-tracking-based motion blur (www.testufo.com/eyetracking) can be a significant slowdown in human reaction time for certain gaming tactics.
