I have a late 2010's iMac running on Bootcamp,

Specs:

Core i3 550 3.20GHz
RAM: 4GB
GPU: ATI RADEON HD 5670 2GB ( 512mb to video)

Your graphics card is a huge problem. I compared it to what I played the first Crysis on where I was forced to change to DirectX9 for the game to run well enough on 1280 x 1024 resolution with some of the heavier settings lowered. I had to lower the settings even more when things got crazy on-screen. Your graphics card is like 2/3 as powerful as what I had back then. I guess you may be able to play but with low--medium settings and low resolution.

I see, then it's better I wait until I get my gaming pc (hopefully) later this year, would you think I would be able to run something like Rage 1? It's a hassle because I check some game specs and my pc should be able to run them well enough, but my gpu is the one that destroys my low spec gaming lol. I can deal with lower graphics, but tearing and bad framerate? Nope!

Should be playable as you surpass the minimum requirements but I do not have the game.

You know what is nice? A desktop where you can change the graphics card later on and thus be able to keep the same basic system for many more years. My computer is exactly ten years old now but I changed the graphics card twice. I honestly recommend just one change after 5--6 years for maximised computing power for your money.

Good thing there are so many old games that are nice to play.
