Every second game freezes midgame
Since the last 3-4 patches, my game is started to freeze every second game. This is independent if I play normals, ranked, ARAMs or other game modes. Every second game crashes. This happens usually around the 15 minute mark, and is independent if its during a teamfight, shop window, standing still, recalling or any other action/non-action. Reproduction rate for me is 10/10. I have to open the Task Manager and close the LoL program, and then reconnect to the game.
I have tried to update my video drivers (NVIDIA GeForce 970) but it did not help. I do not experience this freeze in any other game. I run the game on Ultra settings with everything activated. Using the new client.
I tried to make a search for it, but I get zero relevant hits.
Please instruct if more information is needed (like a bugsplat (does not come up when freezing) and how to get it).
