I’ve used the new client for ~24 hours straight. I always monitor the memory usage of certain apps in the Task Manager. When the client is just started it uses approx 250MB with highest process using 110MB, which is pretty normal. But after all that time the client became very laggy and the highest process was using around 700MB of memory. Everything fixed itself after a restart.
There is definitely some optimisation to do (It may be painfully obvious and may not be the highest priority right now, but I figured that’s why I’m a beta tester, right?)
And apart from maybe some other issues I haven’t found yet, the new client is looking pretty sick
