Since the Scylla patch, the game performance is starting to make the game unplayable.
With one client running, I have a few, but not many, issues.
As soon as I start loading other clients (I have 6 accounts), I start getting horrendous issues.

1. Undocking: 5-20 second black screen - happens on all stations, but is worse in trade hubs
2. Warping on to grid when more than 3 people are there already, fps drops from 60 (with v-sync enabled to cap it at 60) to anywhere between 45 and 10 fps.
3. Swapping between chat tabs causes the exact same issue as #2.
4. Opening industry window causes a freeze for anything between 5 and 25 seconds with an 'eve is not responding' message popping up. If I wait it out, it generally works again, but not always.
5. Activating ship modules consistently causes frame rate drops. As does deactivating them. Heck, dont even get me started on the frame rate drops when I switch modes on a confessor....

I have enabled the downloading of all resources in the launcher, but still, the 'resource loading' icon in the bottom left is running.
100% of the time
on all clients.

I used to run 1 client at everything maxxed out graphically, and the other clients set to 'memory' in the optimisation dropdown
Now I have tried all clients at every possible choice and I still get the issue.
If I tab out of the game, I get random system slowdowns with the clients running - even if they are all docked in station or sitting in a POS with nobody else coming on grid.
