Since like last 2 patches the mememory allocation (GPU) is like 100MB higher, and grows larger with extended playing periods.
Before the allocation capped around 980MB now is goes up to 1200MB.
That wouldn’t concerne me if with that didn’t come with few seconds black screens after respawn.
Spec:
R5 3600
RX 5700XT
16GB DDR4
playing at 1080p
Overwatch at SSD
