Whenever I play this game, my harddrive fills up by an extra 10GB, and then the next time I start my PC it is back to normal again. This definitely didnt happen in previous patches, and it doesnt appear to occur with other games (if it does, it's not as dramatic). The game is loaded on the D drive, but the C drive is the one filling up. Both are HDD, I am using 16GB of RAM and have a GTX 1070 installed. The game runs at 30fps with stuttering, occasionally rising to 45fps on a good server (and 60 in arena commander). edit: I have now set the pagefile to generate only on the D drive, thanks for the help!
