Horrible performance bringing in the 5th toon

[Drommon]

I am having the same problem. Same system configuration as the OP. Let's pretend I have NO technical knowledge... how do I "share" my Wow programs across all cores ? I have no idea where to even check and see if this is happening. I know when I open all 5 accts, my FPS drops down to like 4.3 thanks in advance

In the WTF folder open up config using wordpad. Find SET coresDetected "4" . Underneath that should be a SET processAffinityMask "0" .

Do this ->

SET processAffinityMask "15"

Setting it at 15 makes 1 WoW client use all 4 cores. Do this for each wow folder. You should have a wow folder for each client that is symlinked to a master folder. Once done you will see all 5 clients running on 4 cores. When I did this my cpu resources (Q9550) never goes above 40%. Where as any other combo caused 100% spikes thus causing some characters to fall behind.

Maybe your video card just isn't up to par? I didn't see you specify your video card. I run 5 on a quad 8400 with 8 gigs of ram and my only lag is caused by an older video card.

For those of you who have 8 cores (4 physical + 4 hyper) here is a cool chart to use http://wikizap.mobi/enwow/CVar_processAffinityMask

It also reflects 4 cores. And with affinity set at 15 forces the OS to use 4 cores per client. Even if you are soloing, setting the affinity to 15 will allow you to see some boost in fps.

I7 users should set core affinity to 255 as they have 8 cores (4 physical 4 virtual) though that link recommends 85 probably to devote some resources to background processes

Actually 85 is the physical cores. 255 is 85 plus the hyperthreaded cores. There is evidence (somewhere) that 255 runs a little slower than 85 for wow clients.

I run 2 8800 GTs. Not in SLI - I've debated that, but I isolate each monitor to one of the cards.

My video card is an Nvidia 9500 GS. I've been told it is plenty to handle multiple instamces of WoW

I was thinking... since it, as far as I understand, mostly revolve around the fifth toon, could it be that the setup for this toon is different than the other 3 "adds"?

What im thinking, my setup has the main at full throttle and the rest capped at 20 fps. Maybe this have glitched on the fifth toon so you go full throttle on this one aswell. This might slow your system.

I use a Geforce 9800 GT 1GB ram, and I run 5x wow very smoothly - with the occational hickup in major cities, but I think this is because of loadtime from the harddrive's

Well, I moved to SLI last night, changed my Power Management to Performance (and in the registry per the other post). Those 2 changes actually seem to have made a differance. I am now getting 2-4 frames/sec in Dal instead of 1.2.

Yeah. You read that right.

The major change was outside of the city. Follow no longer breaks and I was able to do HoL without too much trouble (other than the fact that I stink at MBoxing and wiped on the 3rd boss).

I understand what Seldum is saying about adding the 5th - the odd thing is it does not matter which of the clients I close. If I close ANY I am fine.

Heck, even having 1 client not in Dalaran, and 4 in Dalaran, my performance is 20-30fps.

Getting on a bird is the same issue as Dal. Horrible frames (but I don't care - I don't need the scenery in that situation).

Have you monitored your RAM usage lately?

Tonight I experienced lag (5-15 fps on main) in Shattrad city. I looked at my ram usage and each wow client sucked up just under 1 gb. I have a total of 6gb on my system, so I think I have found a bottleneck there....

I wonder if I should buy another 6gb and if it would help.
