like everything from portal 1 spt (except things that are not possibile in portal 2) and how about tas rus in p2?
To my knowledge, you don't need spt for portal 2 because pausing on the 1st tick is easy. Just hit pause when there are only 2 dots on the loading bar not filled up. As for tas tools, they are in development at the moment.
https://github.com/YaLTeR/SourcePauseTool/releases/tag/feb-6-2018 A SPT does exist for portal 2. Unfortunately, it doesn't support TAS due to the nature of the system. It is being worked on though, so hopefully, it'll be supported soon! :)
SAR version 1.14.3 is here. It adds some things and makes some things better. Notably, it unprotects hidehud and fixes a major memory leak in INFRA, so performance and load times should stay high throughout runs. If not, let us know! Full release notes [here](
