Not at all. Im using the GOTR mod and the game seems to stutter and vehicles control like butt. Idk if using an SSD will help with the stutter but I had to move it to my HDD for space issues. I also didnt realize the game was locked at 30 fps till I read this forum. Its free, cant complain but I rather not waste time with this unless I really have a dying need to play it or if the game ends up working better in the future. Could not even complete a simple race cause the stutter and vehicle controls were obnoxious.
My rig is i5 2500k @3.2 and GTX 1070.
The game's PC port is one of the worse ports out there, that's well-known, and many issues were left unresolved. And I don't know why people don't like things when they're at 30 FPS - sure, it's not as smooth as 60, but it's not like it's unbearable to watch. The game's still mostly playable and enjoyable in spite of this. I didn't really play this sort of game before, but trust me, don't let these things prevent you from immersing into the game. It's very much worth it.
Races aren't the only sort of side-mission, you can get through the story mode without them. Try the Septic Avenger (one of the game's most over-the-top moments), trafficking, car stealing, tagging (you can find all spots on the Internet), fight club...
