This was exactly what I needed to get RF 9.5S to work on my Dell G15 laptop after 2 weeks of searching and trying things. It is a new laptop that arrived the same day as RF 9.5S.
This is what I've got:
Dell G15 Special Edition 5521
12th Gen Intel i7-12700H 24MB cach, 12 cores, 20 threads, up to 4.7 GHz Turbo
16 GB, 2 x 8GB DDR5 4800 MHz dual-channel
NVidia GeForce RTX 3060 6GB GDDR6
1 TB, M.2, PCle, SSD drive
Windows 11 Home
The computer recognized the controller, using a powered USB hub, and RF would open and I could see a jet sitting on the runway, but all menu options at the top of the window were greyed out and the entire window was non-responsive to any mouse, keyboard, controller, or screamed inputs... Just before I followed robin74667's above suggestion, I tried the DirectX End User Runtimes install mentioned by csgill75 in this thread. Not sure if that helped with what I did based on robin's instructions. Either way, I'm up and running and I am very grateful for your post, robin74667. I was about 1 hour away from asking for a refund on this product. The InterLinkDX controller is awesome, btw.
This whole thing was not a pleasant experience, RealFlight. You almost lost a future RC customer over this.
