FPS cap vsync

As I have been unable to run ue4 above 70fps at full res in over a year…

Can anyone confirm that vsync doesn’t lock up the rendering to 60fps on 144htz 4k systems?

Would need a 3090 to know, basically. Trying to get one is still like winning the lottery (unless you want to finance some schmuck scalper)

Guess I could test running in 800x600 or less maybe XD
