Steam vs Xbox Pass performance (PC)

[Castex]

Hello, sorry if there is already a thread discussing this topic, I didin't found it.

I started to play TLD when it came available in xbox game pass in PC. I fell in love, obiously, and just some days ago I purchased it in the Steam store to have it "permanently".

I have a midrange laptop (GTX 1050, i5 9400 and 8GB). The game runs really smooth in the Microsoft launcher, but the Steam version runs poorly with the exact same quality configuration. Like, in the Steam version I have several frames drops, even just looking straight to the floor.

Someone had the same experience and knows a way to fix it ?

I'm really sorry about my english, it's not my first language.

Thanks you

Castex
