If you have weather effects enabled, then it is probably lighthouse track, because rain is fps killer in 0.8.1 version :P Performance also depends a lot on number of oponents. It will run much faster with 4 oponents than with 19 (max value).
If you have Arch linux, then regressions in drivers are very probable. I was experimenting with graphics drivers in the past and in very recent versions you need to have specific version of kernel/mesa/xorg driver etc. Otherwise regressions may appear. But you probably know about it if you use Arch
Anyway Intel HD4600 should be enough to run 0.8.1 version in 1920x1080 (I don't say about git version).
