I'm making a game called "karlson RTX", a remake of the game "karlson" by danidev, but it has "RTX" in the name and the game starts with a the way it's meant to be played splash screen, containing the nvidia icon, and soon to be containing it's slogan

will this game (which will be released free, and open source) run into any legal issues? and if so how can I fix them?

I suppose it's free advertising for the brand but you can never be too sure, It also isn't in any way offending the brand if anything promoting it

NVidia briefly describes trademark usage here and here. It sounds like you need to be a partner to use their trademarks, although I think those documents may be primarily directed at hardware manufacturers.

Partners should not incorporate NVIDIA Brand Features into their own productname, service names, trademarks, logos, or company names.

Perhaps more relevant are their general legal notices:

NVIDIA's trademarks may be used publicly with permission only from NVIDIA
