Maybe you should try
Game Stock Car 2013 (GSC 2013).
Despite it's misleading name you'll not drive around in ovals there! In this simulation the term "stock car" refers to a brazilian touring car cup comparable to the Aussies' V8 Supercars. And these are. A. Blast!
There are Formula cars as well: a 70s F1 series called "Formula Retro", a late 80s/early 90s F1 series called "Formula Classic", a contemporary F1 car ("Formula Reiza", called after the producing company) and a F3 car.
Not to forget: There are karts and several circuits specially designed for these as well. And a stock Chevrolet Camaro. And a classic Chevrolet stock car. And the MINI challenge. And there will be free content to be added in the future!
What I really like - no, love!!! - about this title is the sound! Roaring along in said stock cars will give you the chills! Tyre sounds seem to be spot on, too, which makes it quite dramatic if you have understeer.
And because in principle it's rF1 with physics and AI maxed out, it will probably run on your system as well. Give it a try! You can download and try it 60 minutes for free!
