Did a DDU nvidia driver rollback today and forgot to note down my nvidia control panel settings. Luckily I found this post again, anything to add? Somebody was recommending triple buffering but I seem to recall you saying elsewhere that it had no effect on Elite?
My prior recommendations stand.
Triple buffering is an OGL setting and has no effect on D3D titles like Elite: Dangerous. If you want to sync frame rate to a non-VRR display in ED, force fast vsync in the NVIDIA control panel.
