Frame Skipping occurring at random intervals

[desuka]

Hello,

I recently started on P1999, and am trying to play Bard. I am having an issue with swarm kiting though, as for some reason, every 10-30 seconds, there will be a stutter or frameskip, and when that happens I often lose mouse control and mobs chasing me will catch up.

I've already followed the steps in the Dual Core thread, thinking it may have been that. I am running EQ with Affinity set for 1 core, as well as running it in "Realtime" priority. I have turned off all particle effects. My graphics card drivers are up to date. I also can't find any more information via google for anyone having this same problem. The game runs perfectly fine with no issues or lag, EXCEPT for these occasional stutters.

Any ideas on how to fix this? I'd really like to Bard but this is making it completely unplayable.

My PC is a custom build:
Intel i7 920 (Quad core, hyperthreading)
Radeon HD 5850
12GB Triple Channel DDR3 RAM
120GB Solid State system drive
2TB Sata RAID Storage
