Nvidia mode significantly slower than other modes #557

Closed gl00ten closed 1 week ago

Describe the bug When switching to nvidia the framerate drops a lot when compared to hybrid or integrated.

I tested using this: glmark2

System info Please include :OS: Manjaro Linux x86_64 Host: ASUS TUF Gaming A15 FA506II_FA506II 1.0 Kernel: 6.7.0-0-MANJARO Uptime: 13 mins Packages: 1319 (pacman) Shell: bash 5.2.21 Resolution: 1920x1080 DE: Plasma 5.27.10 WM: KWin Theme: [Plasma], Breeze [GTK2/3] Icons: [Plasma], breeze [GTK2/3] Terminal: konsole CPU: AMD Ryzen 7 4800H with Radeon Graphics (16) @ 2.900GHz GPU: NVIDIA GeForce GTX 1650 Ti Mobile GPU: AMD ATI Radeon RX Vega 6 Memory: 3655MiB / 31513MiB

/etc/optimus-manager/optimus-manager.conf

i tried a bunch of stuff. initially i was focused on decreasing power consumption but then i wanted to benchmark

[optimus] startup_mode=hybrid

startup_mode=integrated

switching=nouveau

pci_power_control=yes

pci_remove=no

pci_reset=no

[nvidia]

dynamic_power_management=fine

benchmarking results hybrid [build] use-vbo=false: FPS: 9311 FrameTime: 0.107 ms [build] use-vbo=true: FPS: 10802 FrameTime: 0.093 ms [texture] texture-filter=nearest: FPS: 8747 FrameTime: 0.114 ms

i can hear the fan spin way faster and see the wattage rising in powertop but in the end i get less frames. any idea why?

note: i did change the /etc/sddm.conf file [X11]

Closing as a duplicate of #498 It also might not be entirely related to optimus-manager but, please follow that other issue and post any findings there Have a nice week.
