nvidia control panel settings won work vsync

Lately I've been tinkering with my GPU & being able to downsample to the rift. But it is only marginally helpful since having a variable refresh rate depending on content generation, will most likely show up as jitter in the DK2. Later versions will probably have even higher refresh to further improve latency.Īn alternative solution is something like NVidia G-Sync where the GFX card tells the monitor when to refresh instead of the other way around.

So to actually decrease latency you need to increase the monitor refresh rate like Oculus does by tweaking the Samsung display from 60hz to 75hz. the latency is still limited to monitor refresh (1/60hz). So if you disable vsync and draw at 120hz, the monitor will still only refresh at 60hz (assuming a 60hz screen mode is active) and end up showing every other picture of a mix of both if the timing is off. Disabling vsync does not mean that the monitor will change refresh rate, only that the gfx card stops syncing to the monitor refresh. To avoid unexpected tearing in windowed mode, NVIDIA recommends leaving the V-Sync global setting at the default 'Use the 3D application setting'.Vsync is just a signal for the monitor to the gfx card, telling when the actual refresh of the monitor display occurs. Setting V-Sync OFF now has the same effect in windowed apps as it does for full-screen apps.

If V-Sync is OFF, then there will be tearing (even in windowed mode) because, as in full-screen mode, there is now no desktop compositor controlling the presentation. The OS, outside of driver control, decides which apps get promoted to their own MPO plane. (MPO provides benefits, such as reduced latencies, for gaming in windowed mode.) With multiplane overlay, the application is allowed to present its contents independently and with its own V-Sync setting. However, driver version 461.09 and later supports multiplane overlay (MPO). This means that tearing was avoided by DWM design even without V-Sync.

The Desktop Windows Manager (DWM) would composit the contents from all the windows and then present everything at the refresh rate cadence. Prior to driver version 461.09, only a single plane was available to the OS. Typically, tearing would occur when viewing applications in full-screen mode, so V-Sync is useful in eliminating tearing in this case. When V-Sync is enabled, the application's frame rate is synchronized with the display refresh rate in order to eliminate tearing. Beginning with the NVIDIA Driver version 461.09, setting V-Sync OFF as a global setting from the NVIDIA Control Panel will likely result in tearing even when viewing content in windowed mode.
