It lowers latency by presenting you with frames that are more recent than what you would see at a capped framerate. Really helps improve immersion.
Allowing the GPU to run maxed-out by unlocking the frame rate
adds latency.
With a Variable Refresh Rate display (FreeSync/G-Sync) there are negligible (~1-2ms) benefits to disabling V-Sync and running a game at a frame rate which is even several times the refresh rate, and it has the drawback of adding a lot of ugly tearing.
The best thing to do for latency is use the game's own tools to limit the frame rate to 1-3 frames below the maximum refresh rate - or lower if that's required to keep GPU utilization below 95%.
If the game has no option for this, use RTSS. If you prefer not to use other software, the NVIDIA driver's frame rate limiter is equal to RTSS in most cases, but RTSS is slightly better in some situations (possibly all OpenGL games).
Yes, but it's a LOT more noticeable for games controlled by a mouse compared to a controller. We also don't really know how many next gen console games are gonna support high framerates so I would probably hold off on that for a TV purchase.
You need high refresh rates for VRR to work properly at low frame rates on televisions (and most other displays).
- If a display supports a 40-60Hz VRR range, that can only work for 40-60 FPS.
- If a display supports a 40-120Hz VRR range, that can work with 0-120 FPS because LFC can display 39 FPS at 78Hz, 38 FPS at 76Hz etc.
I gotta say. I am not super impressed by 144hz so far. Though I haven't played a game my old GPU can output 144hz constantly and I am more usually hovering over 80.
Is that an older fixed-refresh 144Hz display, or a newer VRR display?
If you're using VRR, I strongly recommend that you have the game running in fullscreen exclusive mode rather than borderless/windowed. With NVIDIA GPUs I even disable the windowed G-Sync option.
I tested it again recently, and still had serious stuttering issues with
Dead Cells (it's a worst-case test for this).
In this example the game is limited to 60 FPS at 100Hz via RTSS.
RTSS' frame rate display is the orange counter on top, while the yellow counter is the monitor's refresh rate display. Note how it doesn't sync up properly at all in windowed mode, and stutters badly.
If it's a fixed-refresh display you
must be running games at a constant 144 FPS with V-Sync enabled, or 72 FPS with half-rate V-Sync.
Let V-Sync do the frame rate limiting - don't combine it with another limiter.
Anything else will stutter, and eliminates most of the benefit of having that high refresh rate.
ia 60 fpa va 120fps a huge difference like 30 vs 60?
Personally I feel that the jump from 60 to 90 is as large as 30 to 60.
But some people here act like going from 60 FPS to 240 FPS is nothing at all. I'm inclined to think that many either have things configured wrongly, or don't have a display running at those refresh rates.
To be fair, the jump is magnified with sample and hold technologies. 60hz CRT is incredibly smooth. It's the awful motion resolution with 60hz sample and hold technology has that makes it so impactful.
That's very true.
I wish I could get a new CRT monitor.
