So after the patch i have been getting lag running 2 clients and constant screen freezes and about 0.5 fps. So i deicded to go do some fidling. First thing i did was to have a looksie in the bios. I went and disabled the hyperthreading on the cpu. Loaded eve back up and like magic it had fixed itself.

Anyone else having issues with HT and eve?

Yes, EVE is a single threaded client, which often has latency issues when running on two cores in a dual core machine.

HT processors implement a virtual dual core, which add all the compexity of split threads, without a lot of the benefit of dual processing hardware in the middle (two virtual threads share the same logic core in the CPU, so if one thread is using a hardware pipe, the other thread can't).

By forcing EVE to a single core on either a dual core or a HT machine, you can solve a lot of the interworking latency issues, and should find it runs much smoother.

Is shutting down HT likely to have any detrimental effect on other apps? The only seriously processor-heavy things I tend to use are other games (such as Rome: Total War) and graphics software (like Photoshop). And, dumb question though it is, I take it that HT can be reenabled later? I must confess I don't like to tweak the BIOS unless I really know what I'm doing... Shocked

Aye - HyperThreading gives a lot of benefits to apps that are written to work in a Multi-Threaded manner (typically 10 - 15% performance increase over a standard single core system at the same clock rate).

So yes, turning it off can be a pain. However, if you Ctrl+Alt+Delete and go to the processes tab, you may be able to set CPU affinity on the EVE process, forcing EVE to only use only one hardware thread. Not sure if this option exists on all systems, or if HT allows this tho...

disabling your sound also works.
