No. Should I?
No, only 1 monitor. Never useed another, simply my Asus Zephyrus GX701.
I7 8750H, 40GB ram, RTX 2080 8 GB. Win10 Pro.
Trainer does work, I printed out the commands sheet as reference, BUT, it causes crashes on every mission about 5-6 times per mission, no matter which option you enable. Tried from a full on, to a item by item enabling, crashes always occurr.
I just have to try my luck at enabling a cheat if necessary, and maybe 18 to 20% of the time I can complete the mission without mishap.
Last mission, to get max loot and xp, I enabled the insane mode for the mission, and now the mission is l,ocked to those parameters, but without the trainer it is impossible to beat so to continue the storyline.
Maybe a save game editor would solve some issues, like the other ones you have on other trainers, suck as skills, levels, etc. (Yes, I know I should suggest it on the trainer page, but if the trainer doesn't work as is, then no point in asking for more..)
