I'm having the same problem. Used to work fine last time I launched it months ago. Then I uninstalled it, today I downloaded it again and it won't go past the launcher. Pressing play goes back to the launcher, pressing Settings does the same thing, and executing the .exe just does nothing. Tried the tricks described here (run as admin, changed to high performance), still nothing. Uninstalled, deleted the folder, downloaded again, verified files, still same issue.
Intel(R) Core(TM) i3-7020U CPU @ 2.30GHz 2.30 GHz
Intel 620 HD integrated GPU
One thing came to mind: last time I played, I had enabled the Chechnya Mod https://www.matrixgames.com/forums/tm.asp?m=4659800&mpage=1&key=
I thought it may have been the reason, so I unsubscribed from the mod, uninstalled the game, deleted the folder again and reinstalled, still nothing. Maybe there are still some mod files lingering somewhere that I need to remove?
Did you try updating the graphics drivers?
It's the latest OEM driver for my Acer laptop, 126.96.36.19961 date 25/09/2019
The last time I launched the game was a few months ago, with those same drivers.
Intel® Driver & Support Assistant says there's a more recent generic driver but recommends using Acer drivers for stability. Should I overwrite the OEM with the generic driver then?
