[BUG] GPU Caps Viewer: no temp for 4090 laptop with some 3d demos

[hexaae]

GPU Caps Viewer 1.63.0.0.
Some GeeXLab 3d demos won't show up temp correctly with 4090 laptop GPU:

Vulkan - Shadertoy Geomechanical
Vulkan - Shadertoy Seascape
OpenGL 4.0 - Tessellation v1
OpenGL 3.2 - Shadertoy > Coronavirus 2020
OpenGL 3.2 - Shadertoy > Seascape
OpenGL 3.2 - Geometry Instancing
OpenGL 3.2 - GS Mesh Exploder
OpenGL 3.2 - Env Sphere Mapping
OpenGL 2.1 - Cell Shading
OpenGL 2.1 - Shadertoy > Multipass > Alien Corridor
OpenGL 2.1 - Shadertoy > Multipass > Rain Forest
OpenGL 2.1 - Shadertoy > Multipass > Radial Blur
OpenGL 2.1 - Shadertoy > Multipass > Rhodium

will show "-1.00 degC" C° temp (?), e.g.:



GPU Shark 0.32.0.0 (started from GPU tab page) does show the temp correctly.

// ASUS SCAR18 G834JY, i9-13980HX, Advaned Optimus, Laptop GTX 4090 256bit (10DE-2757/1043-21FD Rev A1, vBIOS v95.03.2B.00.30) 16GB GDDR6, 32GB 5600MHz RAM, 18" 16:10 2560x1600 240Hz G-Sync internal screen, external UWQHD 3440x1440 Mi 34" Monitor with Freesync, NVMe, 8BitDo Arcade Stick, EasySMX X10 controller, ROG Strix Carry mouse.

Uh, I noticed it does the same with iGPU:

you can help me by testing GPU Shark 2 and letting me know how it reads the temperature:

Both GPU Shark 2 and GPU Caps Viewer demos use the GeeXLab engine...

Temps are correctly detected by GPU Shark 2.3.0.
But also GPU Shark 0.32.0.0 (started from GPU tab page of GCV) does show the temp correctly... so maybe the problem is in the demos code  itself? Those demos won't show the temp even when running from GeeXLab by drag'n'drop.

Ok. But we recommend you should disable iGPU as Intel GPU.
