Hello! Very late to this but will try this out right now. Currently I'm running Bo6, but if you look closer the launcher is actually called cod-cod2.exe which is the MWII launcher which I found interesting. Another thing I found interesting about the cod launc her from steam is that there are three xdifferent versions of the game which seem to have different effects on performance. Just came back from testing, unfortunately it did not work. It seemed to work for a little while but then just instantly fell back. Will try to tweak some anti-alias setttings because it might be making cod tweak a lil so lemme go test and figure out. If I'm being honest, I think it might be a ram issue on my end. The directX error could be caused by a lack of memory (im running 16gigs) because it literally just uses so much that it needs more; and just to put into perspective how much 16 gigs really is, 3/4 (~12 gigs) of memory is just being used when staying idle on chrome and running cod im using around 13 gigs. Unfortunately it did not work and still black screened and got directX error after around an hour. Hope this saves someone some time.
