I was able to solve my jittering problem by scaling the game up to match the monitors resolution when fullscreen (please tell me if this is a bad idea)
Depends. Does the game window's size evenly divide the monitor's resolution in both dimensions? If so, that's fine. Otherwise, you just introduced more distortion.
now I am moving on to my next problem whenever my player sprite moves at literally a speed of 1 it will blur fullscreen and not fullscreen, I have interpolation set to off and I did the monitor test thing and the aliens looked ok to me, and I also tested this on like 5 different views (tv's laptop, friends monitor, etc) and it persists I have a refresh rate of 144 hrz so I dont think it is likely my monitor here is a link, I recorded it on xbox game bar so it caps the recording fps at 30 but it
I must have looked at 10 articles and never found a solution
if you have any idea of what it is please help!
I appreciate the sentiment of trying to capture the issue on video, but due to how video compression works (which, most prominently of all of its side effects, adds blur), it's a rather disadvantageous medium to choose when trying to illustrate blur. It's a bit like handing me binoculars with a green-tinted lens and then telling me that the sky looks green. Because, given the medium, of course it will!
For this reason, I can't - at least not with absolute accuracy - determine where the issue stems from when the only material for diagnosis is a video.
Please stick to screenshots.
