Thank you for doing your best to try to help me and find the solution. But please do understand the immense frustration the end user has to go through on their end while the developer is fixing things that should not have been broken in the first place.
I shared the error log in another comment under this post as you might have noticed. This may give you an idea of the cause of the crash (the error number reads like 0xffffffff, most of the times, but I have seen other error as well).
Also, as I said, the game crashes quite randomly during the matches (but rarely in game menu or when launching the game). Sometimes I can play for two hours without a single crash. And another time I have experienced 3 crashes in a row within half an hour. It happens both in populated servers during the heat of battle, and in empty servers with minimal activity.
Ah, 0xffffffff is quite a broad crash and could mean and be fixable by a wide range of solutions. So for now, do try to time it and in a few days try the GFN idea for the moment. We will all find a solution, no worries. It is a great community with lots of amazing chaps that always like to help. At the moment its too broad and uncertain.
