Hi
Might be an issue with my Windows 10 laptop but after just downloading and launching the most recent Windows build of 099 (Windows Build 2018.27550) get a black screen in the TD IDE.
Will continue to troubleshoot.
Perhaps I should try an archived installer?
Update
Something to do with my Nvidia Control panel and possibly Nvidia PhysX install
I had it set to highest quality and set it back to auto.
