525.6 Portal launching using BLIT instead of FLIP

With the release of 525.6 and portal RTX, Unsure if this is an issue with portal, on windows gsync works, however since the game is not using FLIP gsync will not work on linux

Does anyone have any idea why it is launching under BLIT, VRR can’t work in this case, all the other games I have tried launch in FLIP with VRR working
