Emulators like snes9x and other classics don't do this. A limiter would still be cool for ppl who use 3D vision. But I doubt alot of ppl with 3D vision still play NES games. I use the "fast" vsync setting on my nvidia card, which basically lets the GPU generate as many frames as it cans and throws out the extra ones.More than likely it is something with 3D vision. It does help a lot with removing judder in games though - everyone is familiar with the experience of moving the camera and it feeling less than fluid (*cough* skyrim is the worst *cough*).ĪFAIK though gysnc is pretty much completely without support in emulators (some of the D3D12 backends might work with it? Not sure). Especially because gysnc and freesync default to vanilla v sync when your frame rate is greater than or equal to your refresh rate. This is obviously something that will vary from game to game so there is no hard and fast rule for it.īased on what I have read, I find the claims that gsync reduces input lag, at least by more than a marginal amount, a little suspect. Sometimes this 2nd option is extremely minor with no noticeable side effects but in many cases this will speed the game up affecting how the game actually plays, especially if the game itself has physics or AI routines tied to framerate. You have 2 options normally here, you can either turn off V-Sync and let the game run at its proper speed but with screen tearing or you can enable V-Sync which will often speed the game up to match your monitors refresh rate (typically 60 Hz). If you notice when you start a game in Mame it will show the game info and the Hz that the game actually ran at. When it comes to Mame arcade emulation though G-Sync is actually extremely handy because the vast majority of games do not run at 60 fps. In terms of console emulation G-Sync itself is actually pretty minor since most systems ran at 60 fps already. This stuff is especially good with the newer high refresh rate monitors and maintaining a 120 - 144 frame rate is rather difficult unless you have an absolute beast of a system or you are willing to sacrifice graphic fidelity. G-Sync syncs the monitor to the framerate removing the tearing. G-Sync itself really shines in PC gaming when your framerate fluctuates which is what will cause the screen tearing. Now you could always turn off V-Sync to reduce input latency but then you will get screen tearing when your frame rate is not in sync with your monitors refresh rate. This means you get lower input latency because V-Sync does add some to all gaming. Well basically you get the benefits of V-Sync without the drawbacks of it. I recommend everyone gaming on a LCD television to do the same thing, whether you are gaming on a living room pc, a console like the NES classic mini, or a playstation/Xbox. For the best experiencing gaming I enable "game mode" and disable all the extra effects, which basically turns it into a big PC monitor. If I leave all of the post processing effects turned on the input lag is way higher. My particular model has been tested and it has an approximate input delay of about 30ms, which isn't too far off real world scenarios for gaming monitors. Personally, I do all of my gaming on an IPS LCD television, and to my eye the input lag is fine. This is because modern LCDs apply processing effects to the frame as it is being rendered to the screen for example, frame duping to artificially inflate the frame rate, interpolation, saturation controls, dynamic contrast, ect. If you are gaming on an LCD television the lag can easily stretch to two or three additional frames. This is as close as we are ever likely to get. The difference in lag between an emulated SNES on an LCD gaming monitor, and a real SNES on a CRT television is about one frame. The problem isn't emulation, it is LCD televisions.
