I tried to find a solution to this problem for months and finally I solved it!!! The trick below fixed it for me:
- Try setting the game’s affinity to one core in the Windows Task Manager process list. You can do this by adding “-onethread” to the Launch Options in the Properties for Homeworld Remastered inside Steam.
