A few pointers to mitigate/fix the freezes associated with SH:DW on Win10.
Right-Click the Games .exe set the Compatibility Mode to Run for “Windows 7”. You can also tick “Disable Full Screen Optimisations” for slightly better in-game frame rate.
Apply and OK.
- Open Space Hulk: Deathwing via Steam (if it isn’t already).
- Open the Task Manager, Go to Details.
- Sort by CPU and find “SpaceHulkGame-Win64-Shipping.exe”, Right Click and Set Affinity.
You will see a list of ticked CPU Cores starting from CPU 0 all of the way up to specific number corresponding with how many CPU Cores you have.
The untick the very last CPU Core and only the last CPU Core.
I found this information on an ancient reddit thread for Deathwing and have found it to be much more stable following it’s advice. The original post talks about disabling more cores, but I found just disabling the last one worked fine, your mileage may vary.
Thanks to [LongLive]Quebec for his great guide, all credit to his effort. you can also read the original guide from Steam Community. enjoy the game.
