I just upgraded to GTX 1070 from a 770 and was pretty excited to test it out. This is the first game I tried out and I am facing issues due to my relatively older CPU. I have a 3 year old i5 3.4 GHz and it seems to be throttling with 100% usage on this game. I have read that it is horribly optimized and this was a known issue but have also read that this was fixed with a patch. However, I don't see any improvement - i am getting frame drops from 100 to 40 which is jarring. On monitoring with Afterburner, I see that my CPU is getting a 100% usage which I believe is the problem. Have tried various fixes from across the web but nothing seems to give any benefit. Lowering settings has no effect & I still get huge FPS drops so am gaming maxed out. I have the latest version with all DLCs installed. Could someone help out please? Thanks in advance!
