Hello i've been crashing all day usually every other pvp match i do with my friends i can get through a few solo but i always end up crashing within 20 ish minutes of playing the game.
Please provide the following information:
CPU and CPU Speed
System Memory
Video Card brand, model, and memory
Windows version
Also, have you verified you have no updated drivers for your system and GPU?
In addition:
Look for a crash folder in the Destiny 2 folder to see if you can find any crash_info.txt files. If you can, load the contents to pastebin.com and post a link here.
Also, on your computer run dxdiag and select the Save All Information option. Load the results to pastebin.com and post a link in this thread.
