Hello, everyone!
My problem is that when watching videos it randomly, maybe very 6 seconds, lags for about a second. It definitely isn't an internet problem. If the videos are at 420p, everything's fine, but if it's at 720p or 1080p it starts lagging. I have a script running which makes every video run in 30fps, doesn't help. I can watch Blu-Ray 1080p videos on my computer, but not on browser..
My PC specs are:
win 7 64bit
Intel core 2 Duo CPU 2.2ghz
4GB RAM
Nvidia GeForce GT 730
I have the latest drivers, my resolution is at 1900x800. I would like to know a solution for fixing this problem. It's so frustrating.. Is my processor too old or what? Nothing's overheating, maybe someone knows what's the problem??
