Thorium is now built with just AVX and not FMA on top of that, as per the description of the previous release. This will allow it to run on 2nd Gen Core/AMD FX Processors and up, and make use of the Intel HD patch to allow hardware GPU video acceleration on older intel chips.
Also, I am now offering portable .zips that besides enabling true portable usage, can also be used to run/install Thorium on Linux distros that don't use .deb packaging. See the README.txt inside for instructions on using. This comes at the recommendation of @Lehner82
