Checking if Alt-tabbing boosts GTA V performance.
Checking if Alt-tabbing boosts GTA V performance.
V sync is active at full 60fps, not a reduced 30fps "half" version. The issue isn't missing the 60fps, but after switching tabs, the frame rate stabilizes near 60fps.
You faced the in-game double buffered Vsync limiting your frames to 30 once it fell below 60. As it approached 30, the GPU caught up and restored the cap to 60—until another frame slipped, then it dropped back to 30. This cycle repeated until you felt a headache. Ideally, D3DOverrider should be active during gaming. Enable triple buffering and Vsync constantly, and disable in-game Vsync. Smooth performance remained even when your frame rate fluctuated between 55 and 60. The main drawback was slight input lag, but avoiding tearing or the jarring back-and-forth between 30 and 60 was better. When you switch tabs or return to the game, Vsync usually shuts off automatically.
GTA V lacks triple buffering support, which explains the issue you're facing. The reported behavior is likely a typical workaround. Another solution is to switch to Borderless-Fullsreen.
Some users might have Team Viewer open in their taskbar, causing it to appear in a window rather than full screen. This behavior is common with many games.
TeamViewer is a remote desktop software that allows you to control another computer from your own device. It often includes features like alt tab and VSync for smooth screen updates.
It enables remote access to your PC using software similar to Remote Desktop.
