Few days ago I've finished main campaign in War for the Overworld. At some point, in the last mission (I think it was once I've started exploring main part of hero dungeon, the one behind magical barier), game became laggy to the point I had literally slide show, pretty much around 1 fps. I had to change game speed to 50% to make game at least remotely playable and finish that mission. I've checked my my video card settings (Nvidia GF GTX 1050 Ti) to see if power management settings aren't set to power saving (I've noticed that MSI Afterburner shows that during game GPU is underclocked to 900 MHz) and changed to maximum performance, the same thing I did for power management settings for Windows. Nothing helped. I'm running latest game build available on GOG Galaxy (1.6.5F1).
Windows 7 64bit
AMD Ryzen 3 1200 @3,1GHz
8GB RAM DDR4-2400 (single channel)
Nvidia GeForce GTX 1050 Ti 4GB GDDR5 (MSI GeForce GTX 1050 Ti 4GT OC 4GB GDDR5)
motherboard ASRock AB350 Pro4
I've checked temperatures, GPU max temperature is 55* Celsius.
