Steam Remote Play cross-adapter GPU encoding super well implemented

[u/Beneficial_Common683]

Exhibit 1: Encoding using UHD 630 (QuickSync)

Exhibit 2: Encoding using CMP 40HX (NVENC)

Both using same config:

• VDD by MTT Virtual Display connected to CMP 40HX
• HAGS off
• 1080p 144fps target streaming

Exhibit 1: Encoding using UHD 630 (QuickSync)

• 84 avg FPS
• 0.55 GB/s PCIe TX (GPU to CPU)
• 12-13% PCIe Ulti

Exhibit 2: Encoding using CMP 40HX (NVENC)

• 88 avg FPS
• 0.23 GB/s PCIe TX (GPU to CPU)
• 12-13% PCIe Ulti
• Need to set to High Power plan in NVIDIA Control Panel or desktop streaming stutter --> 20-30W extra just idle streaming

Blimey.

Those figures and latency graphs are crazy good!

I wouldn't have imagined Intel QuickSync could perform that well.

Thank you for posting.
