Hello guys.

Whenever I try starting a new game or instant action, the process crashes without any any further info.
I'm running Windows10 64 on a i7-4770K with 16GBsof RAM and a Radeon RX 570 with 4GBs.
I'm launching the game from Gog Galaxy.
Would be grateful for any idea.

I have the same problem, how can I disable fullscreen optimization?

Hello,
IWAR 2 runs on my Win10Prof without any problems (as it did under Win7Prof).
But I read, that this Win10 'Game Mode' can cause troubles on older games, so turn it off anyway (pic below).
Give it a try, 'cause IWAR 2 is a fine spacesim with newtonian flightphysics.
Miss that in other space flight sims.

And don't miss this site for very usefull mods e.g. custom_jafs (bigger transport !!!)
