finkleroy: Thanks for mentioning this! I gave up very early on in my playthrough because of the horrible controls and the fact that it doesn't have on-screen prompts for the gamepad. I'll have to give it another go with that mod.
tinyE: I never played it without so let me know how big the improvement is.
I do know even with, some of the controls were odd, but you could remap them, save for the menu screens.
I never did get used to leaning forward and backward in the car, which I never really used TBH.
I know that the GOG version of the game is playable but when I first started playing it, I had a 750ti and the frame rate capped out at around 40 with the unlock. Gentlemen of the Row, I believe has no way of fixing that and I have contacted IdolNinja on GOG about it and he confirmed it as well.
I think the Steam version might run without the client, I believe it actually does at least for linux. There's a chance it might for Windows as well but that's just because I like more frames. The GOG version is perfectly playable, however.
