Hi, I’m using the Nvidia Capture SDK :
And it seems that using NvFBC is breaking G-Sync (even the NvFBCCUDAAsync sample code breaks G-Sync while running, indicator print “Normal”, previously printing “G-SYNC”). Enabling the Graphics API Visual Indicator shows BLIT for applications that were previously using FLIP. Running NvFBC also cause screen tearing for all applications, so I guess it also breaks VSync even if the indicator says it’s enabled.
Tested on :
Ubuntu 20.04 / 20.10
Driver 460.39 / 460.67
