At least on Series X they fucked up the graphics, there's worse pop-in there's really bad texture loading of the road even below your truck if you're stopped, in some cases it's even worse. I've also heard the same complaints about the PS5 patch.
These guys are more interested in making DLC than making a good product for it's customers.
They aimed for 60FPS 4k which is way too ambitious for these morons, they should have given different video modes and resolutions instead of this.
As for DLC these fuckers are the worse, they have Season Passes and then they keep making more DLC trucks that are outside of those Passes... because ??? Simply greed.
Fuck these guys.
I loved Mudrunner, and this game started off good, but these guys are too greedy and have no fucking clue what they're doing.
If you check the sub you can still find on the regular people driving on a paved road and their truck flying up in the air, because the physics are so bad. It's almost impossible even with the correct tires to drive STRAIGHT on a paved road due to how shitty the physics are.
As for relaxing, it's filled with too many many map spanning objectives, a few of them would be fine, but even on the first map some of the first few objectives will take you literally 1 hour, and that's if the physics don't fuck off and destroy your run by throwing you off a bridge randomly tossing your cargo in a hard to reach place. This game should be relaxing but it's poorly designed.
