A V-sync and G/free-sync topic for classic games
A V-sync and G/free-sync topic for classic games
This idea came up while I was thinking about purchasing a new PC after reviewing Ryzens benchmarks and deciding on a processor. I’m planning to install a 120 Hz monitor, choosing between G-sync or Freesync based on the graphics card. The game I’m interested in is UT99 GOTY edition on Steam. If you don’t use V-sync, it causes significant frame drops, but unlike games such as Half-Life, it actually improves performance. It even boosts speed on my current machine—without V-sync, it runs about ten times faster. So would G-sync or Freesync prevent this, or would V-sync still be necessary?
with a 144hz Gsync display and Vsync enabled, the game will cap at 144 frames per second. if you leave it off, it will sync with the monitor up to that rate before exceeding it, similar to a regular monitor. however, rendering at 200fps still shows no screen tearing, which is unusual. it might be too fast for your eyes to detect, or something else is affecting the display. you usually enable Vsync, and Gsync remains active in the NVIDIA control panel.
I understand your friend's situation with V-sync still active while G-sync is enabled. It seems V-sync could interfere with the benefits of G-sync, potentially reducing its effectiveness. If you still want G-sync advantages, turning off V-sync might be a better option.
Enabling V-Sync adjusts the game's frame rate to match your monitor's refresh rate, reducing tearing. It works even if your FPS is lower than the monitor's refresh speed, capping it at half that number. For instance, with a 60Hz monitor and 73 FPS, you'd be limited to 60 FPS. If your frame rate drops to 59 FPS, V-Sync restricts it to 30 FPS to display two frames per second. Triple buffering is another technique that prevents noticeable drops to 30 FPS by pre-rendering extra frames, though it demands more processing power. V-Sync also brings its own drawbacks, notably input lag, which can be more pronounced in certain games and affect multiplayer performance. Triple buffering adds even more delay. G-Sync and Free-Sync were designed to complement V-Sync, but using them together is no longer advisable due to increased input lag. Instead, consider a FPS limiter like RivaTuner, setting your maximum below your monitor's refresh rate. Avoid tools such as NVIDIA Inspector as they replicate the lag of V-Sync. Fast Sync is similar to triple buffering but with slightly less delay, suitable only for NVIDIA GPUs and requiring higher FPS—around double your monitor's refresh rate. It’s best to steer clear of errors and opt for solutions that minimize input lag.
