The official statement also mentioned the issue of VSync, but they only suggested turning off VSync and did not explain how to disable DLSS if VSync is to be enabled.
Moreover, I had conflicts with VSync even before I enabled Frame Generation.
I have tried the commands r.NGX.enable 0 and r.NGX.DLSS.enable 0. When executed, the screen flashes for a moment. It seems that the commands are effective, but they still cannot solve the problems of latency and vertical synchronization, and the effect of DLSS still exists. It seems that it is still affected by DLSS.
