The latest patch seemingly results in a massive improvement for most players.
After an absolutely disastrous launch, it seems like Marvel Rivals can still pull through with some very fast and very efficient patches.
Recently the game underwent a maintenance to address the game's horrible performance on PC, and judging by the reactions, it actually worked.
For the most part people are talking about much better performance, even running the game at stable framerate on older GPUs and handhelds like Rog Ally.
Chris_F mentioned that matches against PC players also felt much better as a result, no longer resulting in random rollback spikes.
Meanwhile, Chris G was less enthusiastic, outlining that the prior stability issues have already made a lot of people leave, even if the performance is now better.
Also worth keeping in mind that the anti-tamper is still in place, and while the game runs better, modding it and extracting info for better labbing tools and wikis is going to be very difficult if not impossible in some cases.
