Massive Framedrops/Stuttering on SRS

So I play SRS this league and every once in a while (like every 1-2 hours) I come into an area where I get massive lag and framdrops as well as sudden speed ups from the lockstepmode. I cannot reproduce this bug, some tilesets seem to be more prone to it but a zone restart still might fix it. This poblem just killed me in the last round of Uberlab while the rest of the lab was mostly fine (minor occurance in the prison tilesets).

I have died to this about 5 times this league and my pc could usually handle even coc builds just fine (some crazy ones still wrecked it but unlike other ppl I didn't crash mostly).

I have the same Problem!
Still I'm not sure why an when that happens, but it is extremely unplayable when that happens. I have found a video were RaizQT tried to describe a bug, but in that video it is not as extreme as it is on my pc - so i don't know if it's the same source of trouble or a new "bug".

My frames are normaly realy stable(Core i7/ nvidia 650TI/ SSD/ 32GB RAM). When I spam SRS I always get Ping-Spikes which at least double my ping. Normal ping is about 30. When i get in the "Lag-Of-Death" it's between 60 an 600. When it's unplayable It seems as if i first play in slow-motion and then suddenly the game tries to get back to realtime and everything is extremely fast. This repeats until I end the map. While leveling I never had these issues.

i'm experiencing the same issues playing and auramancer (low life 9 auras Necromancer) srs build, but its constantly... not only every few hours.

when i go full throttle with offering, vaal haste / clarity i get kicked from the server.
its really unplayable.

not to speak about partyplay...
