This seems to be the best post describing the issue so far, explaining that the GPU's VRAM is below max when you first load the game, then gradually it climbs until its beyond Max, during the time causing stuttering until eventually it crashes the game to desktop.
Crashes either during the main menu, during spawn selection or during gameplay with no error to show, just straight to desktop.
The gameplay is constantly stuttering in bursts, making it unplayable and then it inevitably crashes.
I had no problems whatsoever during the beta, no changes to hardware, all drivers and software updated.
If i get through one match and then exit to the main menu, check my graphics settings, i can see my GPU VRAM is beyond the Max threshold, when i first started it was way below the max threshold. Theres definitely a problem with memory leak imo.
Tried lowering every setting to Low, same outcome.
