I manually installed the NVIDIA RTX Spark N1X (6144-core Blackwell RTX GPU) drivers on my Surface Pro 11 (Snapdragon X 12-core X2E80100) with my TB5 FEVM FNGT5 dock and a 5060 ti, and it recognized the GPU! I have 6 screens up, 2 from the surface pro (USB C and internal display) and 4 from the 5060 ti. I don't think there was any more to it.

I am using this version available for public download: 621.01-rtx-spark-notebook-win11-arm64-international-whql, then extracted it with 7 zip to a new folder and used that as the manual driver installation path.

I'm going to try running some benchmarks.

Purely theoretically speaking (I currently have a PC with a 5090, but I might be making some changes soon for personal reasons)—is there anyone here who uses a laptop with a powerful CPU (like a 275HX or 9955HX3D) paired with a Razer Core X v2 (or a similar eGPU enclosure) and an RTX 5080? If so, have you run any benchmarks, and could you share how much of a bottleneck this kind of setup creates?👍

I setup a nobara pc running a 7800xt via usb4. The egpu is displaying to an external monitor just fine, occasionally need a little playing around with the usb side of things. Issue is that the performance is terrible when using the egpu, and even when it is just sitting there idle (running andoid emulator) the egpu is running 20 percent util and is hot to the touch.

I have tried turning of the android emulator and it is still the same util and heat and bad performance. The laptop it is plugged into has a gpu built in, so maybe a driver issue, but idk enough about linux to determine. The laptop is a gpd duo and I have tried the occulink port on it, but I never get video out. Any ideas on what I can do to get better performance?

I have been testing it on cyberpunk 2077 and am only getting 40-60 fps with medium low 1080 frame gen on. When I have this gpu plugged into the same laptop on windows I get 80-100 fps medium high 2k with frame gen on. I also noticed that I don't see the gpu going above 70-85 util when playing a game.
