@trancemixt hey buddy, did you try a workaround mentioned by Jim during the public beta patch update:
https://www.reddit.com/r/commandandconquer/comments/hrrh2y/remaster_update_and_july_beta_patch/If you saw increased framerate stuttering or launch crashing after the June major patch versus the launch version, we have an experiment you can try:
Go to your C&C Remastered Collection page on Steam
Click on the Manage button (gear icon)
Select Properties
On the General tab, select “Set Launch Options…”
In the box, enter “NOSPLASHPRELOAD”
Click OK and launch the game
This will effectively revert the texture optimizations we made in the June Patch, and may help performance / stability with certain hardware configurations (This launch option will also work with the standard live branch as well)
