I play on the Europe servers and used to have around 80 fps before the mid-season update, but richt now its around 30 in practice range and my game crashes in quickplay. Is this my laptop or are it the servers?
No, I’ve been getting these issues too. My PC isn’t super high end, as it is on the older side (standard gaming desktop set-up) But pre-mid season patch, Overwatch ran perfectly fine. I never had any issues playing it, had really good ping (roughly 25-30ish mbps) and my fps stayed around the 160-170 range.
After the mid-season patch however, quality TANKED. I got massive fps drops, hitting 4fps, latency spikes towards 80+mbps and reaaaaaally slow loading times.
Figured it was something on my end, so I did anything and everything I could. Updated gpu drivers, cleared any and all cache files relating to OW or Battlenet, repaired and reinstalled Overwatch files, you name it. Nothing worked.
Any other game? Halo, Fortnite, GTA? All of those run smooth as butter.
I think what it is, and I can be fully wrong here but, I think it’s a combination of things that are building up to a perfect storm. You have WoW forever releasing and the Devs who struggle to optimize their game. Something like Overwatch should run a bit more on the GPU side of things but it CHUGS your CPU. It’s the only game where I’ve had to fix multiple memory leaks and trouble shoot so many bugs, and their servers are held together with the whispers of a better future.
Basically, I think they redirected some of the server capacity towards the release of WoW forever, or something I’m not a server technician so I can’t say for certain. But I think that could explain why some people are getting Chicago (ORD) servers and the rest aren’t (Vegas servers-LAS1). Coupled with the devs not really optimizing their game… I think that’s why it’s been struggling.
I hope they fix SOMETHING in the future (preferbly NEAR future but who knows).
Anyways, sorry for the text wall but I hope this helps you get some clarity on the issue. I’ve been seeing a lot of these reports and not just on here. But hey in the meantime you can always buy the Doki-Watch bundle 
(seeing as the shop is the only thing working LMAO).
Same problem, after mid seassom patch, fps drop from 140 to 60 every second.
