I use a quad core with 16gb of ram and an ssd for the operating system and don't get any lag running 7 accounts providing I have everything turned down. I have a 2 gig graphics card which helps I think but my rig is by no means high end.

well i put my whole pc together for £350 about a year and a half ago. Treat yourself, your worth it!

Client optimizations would be really nice certainly a good QoL thing. Might even entice me and others with low end hardware to get another account, Jast saying.

I agree with the OP and want to reinforce what Ville has posted as well as others. 

I have returned after a long hiatus and I find the client is now far more resource hungry.  It's okay with two clients running but sends my upgraded P/S into hyper drive constantly.  Three clients are no longer possible.

I like to run a miner just sitting there extracting, then harvest with my Symbiont guy while my combat guy autopilots to assignment locations.  So really, I only need/want high end graphics during combat for the pew pew visuals.  It would be nice to be able to tone down client resource needs for the non combat toons.

UPDATE :: I did some empirical testing by comparing P/S temp (work) with graphics "as is" (maxxed) versus all graphics to min values except draw distance - I got about 25% reduction in average P/S temp with spikes consistently present when leaving terminals, teleporting, i.e., when ever mass changes to data or graphics ensue.

Now, my graphics card and P/S were high end upgrades two years ago.  I'm thinking the real answer is to upgrade my whole system.  Since I can't do that right now ($$$ issues) I guess I'll have to live with wimpier graphics.

i hope you guys play with V-Sync on.

I remember my old system overheating from 120+ FPS while in terminal or on login screen. also deactivate all the fancy forced filter in your system settings.

I want better optimized clients so I can run more accounts on a machine
