Hello, I'm seeing a much worse performance on Ubuntu 18.04 with an Nvidia 1070 and i3770k @4.5GHz and the latest stable drivers. To the point that MGS2 runs at down to 50% or 60% in many scenes.
The bottleneck is clearly when running in OpenGL Hardware mode and it slows down even when running at default resolution with every performance heavy option turned down.
This is with the stable 1.4.0 version and with the latest build of 1.5.0, also tried the different SSE4 AVX versions of the GS plugin with more or less same results.
On the other hand, I've tried the latest stable Windows version and using OpenGL I see no slowdown at all. Which is weird since I read everywhere that the Linux performance issues were in because the OpenGL renderer is slower than the DirectX one, but there also seems to be that the OpenGL renderer runs much worse on Linux.
Is this a known issue? If not, what' s the best way to debug this?
