Input from those running multiple accounts on one machine.

I run 5 using a 950 OC'd to 4GHz and 24GB of ram. I'm also using 2 MSI GTX 560 Ti's OC'd to 950/1900/2100. I use 2 1920x1200 monitors and run the game in FS at 1920x1200.

I play on the low setting and get 40-45ish fps on the main screen.

IMO, the biggest performance bottleneck in Rift is CPU, then RAM size, then GPU.

Agree with this.

I have an i7-920, 12Gb of RAM (upped from 6Gb this week for Rift) and a single 470GTX, overclocked to 480 levels.


Single monitor at 1920x1200, I could only run 3-4 clients. Overclocked the CPU to 3.8Ghz and get 40+ FPS with 5 clients on one maching using ISBoxer.

I completely agree with this, and is why you get the largest performance increase by overclocking your CPU.

The other thing I noticed last night while playing is that one of CPUs in 80% or so loaded while the other three are like 40%. This is from memory, so I will confirm tonight but I know one CPU was working alot harder than the other three.

JamieW: Are you using ISBoxer? If not, you could try setting the other clients to use window mode and then scale them down and see if that helps.

All clients launch set to run primarily on Core 3. You can configuer each instance to run on different cores in your .cfg files ( if windows lets you >< ).

Note Amrathes comment :

There is another thing you need to do in Rift to make it load balance onto another core.

In the rift.cfg for your characters located in C:\Users\<username>\appdata\local\RIFT (the files are virtualized, so you will see <Charactername>-rift.cfg) look for a setting called Main CPU Thread (it defaulted to 3 on my i7 920). Change that setting to a different core for each account (in my case I set it to maincputhread = 3 on one character and maincputhread = 5 on the other).

If you do that, you will have the primary thread for each account on a different cpu core. After making that change I went from core 3 tapped at 100% to core 3 and 5 tapped at about 80% each.

Set different clients to run primarily on core 1, 3, 5, 7 in the listed file.

Note I found this file in C:\Users\<username>\appdata\roaming\RIFT not C:\Users\<username>\appdata\local\RIFT

1 CPU may also work harder as other applications running may be using slices.

I'll have ISBoxer for each client to it's CPU and see how that works.

[Berserker]

I believe you can also set you maincputhread = 0 in the main cfg file (*before* starting your set with the wizard, or all of em if you've already done so) and then ISBoxer will be able to do its assignment magic. I mine was set to 0 during beta (was running a core 2 duo machine then) and see load balanced cores when playing on the i7 now.

[Krago]

So, I had ISBoxer assign the clients to a seperate core and now everything is as it should be.

I also capped the main window to 25FPS and the background ones to 10FPS and it's a lot smoother now.

QQ

My system :
GTX 280 + OC Quad core + 8GB of Ram + eVGA nforce 790i MB



2 clients perfect (with high settings)
3 clients doable (with medium settings)
4 clients doable (with low settings) but flaky
5 clients undoable (with lowlow settings) /follow moves clients in all directions, because they try to follow each other and then move away ..

cores allocated : 1 | 2 | 3 | 4 | 3+4 (capped to 20 FPS/10FPS)

waiting for my upgrade to arrive:
* i7 950 / 3.06Ghz
* ASUS Rampage II Extreme RoG
* 10 GB Corsair Dominator Memory
* ASUS EAH5870/G/2DIS/1GD5/V2

Hopefully this will enable 5 clients at decent settings.

(My old system was running perfectly for 5 clients WOW)

Let me know how that 5870 works out for you Bloodcloud.

I have a 4970 and want to wait until the 7 series comes out as I try and upgrade every third model release ( if possible ).

I have been contemplating building a 2nd system around an AMD X6 and using it as my main multiboxing rig, or pairing it up with my current machine and runing them in tandem.
