You're massively exaggerating. The latency added by gsync is not even worth mentioning. Vsync latency (in games that don't implement a low-latency vsync) is **MASSIVE** compared to gsync. The reason CS:GO benefits from very high frame rates is not due to latency, but due to image clarity. The higher the frame rate, the more stable the image due to less tearing and less micro-stutter. With gsync you don't have that problem to begin with. And all your settings are doing is make the game look blurry due to upscaling, which makes it more difficult to make out small details. In CS:GO, better visibility is an advantage. Also, running non-native resolutions adds about the same amount of latency as gsync does. Doing interpolation requires buffering of a few lines of the current scanout before the upscaled result is displayed. But nobody can tell and it doesn't affect anything. That's how low it is. If you were trying to avoid any latency you would use the native res of your monitor. If you wanted 4:3 without latency, you'd need to have it non-stretched using your native res. On a 1080p monitor, that would be 1440x1080 non-stretched. Anything else and you need scaling, which adds latency. But you're not doing that. And that means you get extra latency. Yet you think you have avoided any sources of extra latency and that anything else would get you 1-shotted Furthermore, if you watched CS:GO tournaments on Twitch, you sometimes see some professional players sit in front of a monitor that appears to have a weird flicker. That's motion blur reduction. Some pros enable the strobing mode of the monitor to reduce motion blur. That also adds latency, same as gsync or even more actually. They don't get "1-shotted", now do they ;-) I did some tests where I enabled vsync in the game (yes, VSYNC) at 144Hz, which produces input lag that's way worse than gsync, and guess what? I was playing *almost* just as well. The mouse felt a bit different which messes with muscle memory.
