This happened only recently. Whenever I open a game there’s intense lag when I try to move my camera, move around, and even playing the game. The only time where there isn’t that much lag at all is when I’m inside a script.
Another thing I should add is that this is what my roblox studio looks like when I try to launch it, I have to go to file then recent games to go to a game I want to work on:
It means that your computer isnt strong enough to run Roblox Studio, it could also mean that your system is not 64-bit. It may also mean that your graphics drivers may be out of date and incapable to run such programs.
