I’ve just created a thread there: UT not working with NVIDIA Optimus - Debugging, Optimization, & Profiling - Epic Developer Community Forums
But I don’t really think they can help me, because someone with an equal problem created a thread on the and was directed to the unrealtournament forums, to get an answer (Epic Game Launcher freezes at start - Getting Started & Setup - Epic Developer Community Forums ). There no one replied to his thread and was left alone with it (Unreal Tournament ).
Don’t know, if Epic Games / UT developers don’t care about this problem, since only 2 people are getting this issue right now (I think there must be much more, because more people are using gaming laptops with two GPUs)…
