I'm trying to use PCSX2 from the daily PPA on Ubuntu 17.10. My hardware is an 8700k with an Asrock z370m ITX motherboard. I'm not trying to run in hardware mode, only software, because I do not have a dedicated graphics card. With this setup I can run most of the games I have tried so far ok in Windows 10; however, I'm having issues with performance in Ubuntu (also same in Archlinux). I'm using the latest mainline kernel 4.15 which has the drivers for coffeelake gpus. I have also tried the ubuntu kernel which also gives poor performance.
Here is a screenshot showing slow performance from a game that runs fine in Windows: https://imgur.com/a/hO0jH
It's only running about 50% speed even with 6 cores enabled in software mode. As I mentioned earlier, it is also poor in Archlinux with a git build from AUR. It is a simple 2d game. Other games like Metal Gear Solid 3 also run worse in Linux.
Another problem is that the compatibility is worse. For example, both Quake 3 and Unreal Tournament fail to load into actual gameplay, locking up at different times during loading. These games work fine in Windows.
