If i set real_timestamp_tolerance to 1, it shows 24/1000 fps but panning scenes move choppy exactly like original 24 fps, meaning it moves like 1x with scaling effect ON.

Where is the black insertion setting and what does it do?
For performance increase, just change HDR support checkbox to OFF, that's the real memory hog.
After further tweaking, i think these settings actually improve smoothness, giving stable fps:

Thanks Ricky!
But why do you need 1000 fps? You have 1000 hertz monitor? Your settings just prevents LSFG from work, but continuously synchronize to monitor, which is an trick btw.
Frametime_buffer_size: should be higher than 3 for general frame generation workloads (1 will prevent to generate frames)
Real_timestamp_tolerance: by default, Fixed generation modes use own presentation tolerance, not applicable for overlap values.
Note1: Why buffer higher than 3? Because LSFG will stutter time-to-time even with huge headroom, tested, tweaked, always the same, cant say about 50 series users!
Note2: About overlap values, for example, when you set tolerance to -0.51 for Fixed 2x LSFG mode, you will see weird flashing artefacts, -0.50 works as intended!
Queue target: the difference between 0/2 vary about 80% extra latency in cost of better handling capture variations!
Max frame latency: theres no dramatic difference between 3/15 value, for me, during Crew Motorfest (capped 60 fps online game), 0/4 works better than 1/3 respectively!
Capture: WGC is not reccomended at all, because performance suffers under high GPU loads, but deal w/overlays, DXGI will work worse with overlays, but doesnt suffers too much, like video capture, Discord, etc!
Only Windows 11 users can use WGC for latency purposes, measured WGC under medium headroom, lower than DXGI queue targeted to 1! Insane? Yeah, but not neccessary!
