I am also having the same issues. It has only started with the current season. The game will launch but then hangs in the loading screen. Some time I will get into the game but then have horrible lag spikes or complete game freeze.
I have done a full trouble shoot on my end including game file scan and repair via the Battle.net agent and driver updates.
PC specs:
- Windows 11 Pro 64bit
- Ryzen R5 1600
- NVIDIA GeForce 2070 SUPER
- 16GB DDR4 Ram
