OK so I remember this bug from .62 with cars where after awhile of driving you drop frames (you go from 60 FPS to eventually only 3 after about a hour of driving) the only way to fix it was by completely restarting the game. that's what's going on here in the recent .63 updates (after jumping) after about 30 minutes of playing the game slowly loses its frames and the only way to fix it is by restarting your game, considering I use a low end PC this really affects me (also every time you fire a gun it freezes but that's cause of particles) and probably other people with low end PC's so if you could please figure out what this problem is with the engine (it's a engine bug cause the problem with the cars in .62 was because the engine couldn't support the wheels) than I can finally play this game constantly
