Hello. Sorry for my English first. I am using latest dolphin, stable and beta and development versions and ishiiruka versions. I have got problem with perfomance of dolphin with external gpu (gtx 660). My PC is All-IN-One MSI, windows 10 x64,latest nvidia drivers, high perfomance power plan, i3-2100, 12 Gb DDR3 RAM, nvidia gt 540m and now i plug in external gpu through chinesse adapter. And my pc boost in pc games and other emulators. But dolphin works strange in 3d games (wii sport resort, super mario galaxy, punch out, etc). GTX660 100% usage and 30-35 fps. Even in 640x360 resolution. And fps doesnt change if i change resolution from 640x360 to hd or full hd. Without external gpu on gt540m same games works fine, even in hd resolution. So why external gtx660 works with dolphin much much worst then internal gt540m? For example cemu (wii u emulator) have good boost with external gtx 660 and use this gpu correctly but dolphin use this gpu 100% and give 30-40 fps even in 640x360 resolution.
1. FPS 30-40 doesnt change with changing resolution from 360p, 720p, 1080p.
2. 100% usage of gpu even with 360p resolution.
3. Same games works fine with gt540m even in 720p.
4. Other emulators and pc games have boost with external gpu.
5. FPS and perfomance doesnt change if i change backend (vulkan, directx 9,10,11).
Help me please. Its very strange situation.
P.S. Forget to say that gtx660 work through pci express x1 port 5gb/s. (WiFi port of my oc).
