Windows vs Linux (x64) - TetsuK - 06-11-2019
Hi,
i have a Intel core i3-2310m and his integrated GPU (HD 3000)
I've tried Dolphin 5.0 on many OS on three games And here are the results :
Renderer : OpenGL 3.1
Deepin 15.10.1 , Manjaro KDE, Parrot 4.6 KDE
- ~30fps on Resident Evil 4 GC , Legend Of Zelda TP GC and on MHTRI Wii
Windows 7 64 Bits Home and Windows 10 64 Bits HOME (1903)
- ~27 fps enter in game (menu) and ~17 fps in games on Resident Evil 4 GC and LOZTP GC
- ~30 fps menu and ~1FPS
in gameso I dont understand how it's possible.
does that mean that Dolphin is more speed on linux????

It sounds like this has to do with the drivers for the HD3000 on Linux vs. Windows. Linux distros use Mesa as the driver, and Windows uses whatever Intel makes for it. There is a lot of time and effort put into Mesa (a few different companies actually contribute to it) so it's very robust in many regards, and from what I understand this can translate into higher performance on Linux in comparison to Windows. I believe this kind of stuff has been documented on Phoronix a few times before.
So, it's probably just an instance of drivers on one OS being better than another. Not sure there's a huge difference in other hardware (such as AMD or Nvidia GPUs). Intel iGPUs are a special case it seems where the performance disparities are that pronounced.

I also think it's because of Mesa, it's miles ahead of Intel drivers on Windows (well, at least for their older iGPUs, can't say about the newer ones). For example, the Intel HD 4000 from my laptop is limited to OpenGL 4.0 and DirectX 11 on Windows with the Intel drivers, but on Linux with Mesa you get OpenGL 4.6 and even Vulkan support with this iGPU...

thanks for the answers.
