Beatrice Belleza School of Applied Knowledge	Posted - 2006.12.27 00:33:00 - [1] Like the subject states I was wondering if theres a way for someone with a dual core computer like myself have 2 clients open with 1 core dedicated to each client? So Core0 for the first eve client And Core1 for the second eve client Anti-Roid Machine!

ClawKnight Veto.	Posted - 2006.12.27 00:49:00 - [4] CTRL+ALT+DEL Processes tab Right click each Eve (probably called ExeFile.exe): set affinity On one tick 0, on the other tick 1 - should work :)
Bentus Kushani	Posted - 2006.12.27 00:56:00 - [5] You don't need to. Let windows handle it, it'll automatically split the calls between the two processors, and it will do it better than you can.

MrRx7 Amarr Quantum Industries Prime Orbital Systems	Posted - 2006.12.27 03:39:00 - [7] thats not true, eve is not a mult-threaded app or so Ive seen. so spliting the processes can help, but then again spliting will do no harm either.

But if you like to know that you ,yourself, split the clients between the cores then go ahead and split the affinity, but I havent seen any noticeable differences between doing that and not.

Mmmm you should learn how windows handles threads and load balancing. If one core or cpu is under more stress the next thread will be put in the other core so letting windows do it is far better then setting to one core only. Multi threading just allows you to process more then one thread at a time when possible. ----------

Grez Minmatar The Raven Warriors	Posted - 2006.12.27 05:11:00 - [12] Doesn't matter. Windows will seperate the DX calls and such between the cores. Also, the way EVE is engineered, means that the moment one client loses focus (you de-select it), it uses much less processing power. There's really no need. --- Cache Clearer

Tonkin Black Lance Against ALL Authorities	Posted - 2006.12.27 07:21:00 - [14] i dual account on my computer, and your computer will automaticly split the cpu. i find it runs the same, but i have my accounts on different partitions and on a raid 0 array. plus i have 2 7900gtx cards but its better the heave each account on a sepate hdd or partition i find, runs laggy on the same partition, dunno why ask bill gates
Roemy Schneider BINFORD	Posted - 2006.12.27 07:33:00 - [15] 'bout the hdd stuff: eve writes/loads a heck lot. dunno how far partitioning really helps as the heads still have to run over the same drive; i found it to be just another form of folders with a little less fragment chaos. but a client on its own drive would be preferable. oh, and an extra one for windows with it's own temp file(s) - this helps your entire windows life anyway ^^. raid 0 is cute and all but looses quite a bit of performance with all these tiny kilobyte files - dunno how far NativeCommandQueueing helps these days, though; i'm still on SATA I RAIDs
Khalm Amarr	Posted - 2006.12.27 08:20:00 - [16] i am running 2 clients with intel core 2 duo prosessor and clients are not set to run in specific cores. both clients run smooths as silk. i could imagine them running any better. --------------------------- Khalm's lazorz say pew pew

I also have 2 wd raptors @ 10 k rpm in striping , before i ran on each raptor 1 client and i have the feeling that it worked better like that instead op the striping that i started using recently . The prob prolly is that the os and clients r both on the same disk wich resulst on periods of heavy load , i should prolly do better with another raptor just to install the os on and keep the stripin raptors for gaming .

And if you have a super graphics card anyway, then the chases are that you have a powerful enough machine to handle both clients smoothly anyway. --- Slot 10 Akemons Modified 'Noble'Zet 5000 implant +8% Armour FREE
konkord Knockaround Guys	Posted - 2006.12.27 11:26:00 - [19] Yea, i run 2-3 clients of Eve on my PC (specced below) and it seems to run everything fine without adjusting the CPU affinity. In fact, what with the defocus CPU reduction someone else mentioned, i get 70 FPS in pvp on my focussed client because the other clients are 'idling'.

Ormen Tuttle	Posted - 2006.12.27 11:57:00 - [20] I agree that there is no need to dedicate. I've run three clients on mine and let the computer handle it and they run great. CPU: AMD 64 FX-62 Video: Radeon X1950 Crossfire 512mb each Memory: 2 GB
BBQ Gallente Suicidal Tendencies Ltd	Posted - 2006.12.27 14:24:00 - [21] There was a bug ages ago with DirectX that people had to work around for dual core systems, this was fixed with the 2nd revalations patch though so no more splitting cores (even though some on the forum still insist that you must do it). I run 2 clients on my rig AMD AM2 X2 4200 (at 2.8GHz) 3GB DDR6400 (80MHz) ram, running at 800MHz XP x64 ATi x1900GT PCIe graphics 2x 19" Monitors I set one client on each and it looks very nice with the aility to swap clients by just clicking on the one I want. Using dual screens also allows you to keep an eye on both and attend to the one that needs your attention. Splitting the games over 2 cores by forcing the clients onto a specific core may get you 1% more speed at most BUT you loose the ability of windows to manage the processing power. effectivly. This will be more prevelant on Vista Ultimate as it includes thread optimisation for dual core systems (MS left the optimisation out of lower versions as it only gives at most 1-2% speed improvment). The thing to remember is that its not just the game that is split across the cores, there is also drivers and background tasks that get split across the processors. By forcing the cient you effectivly tie up one core with eve and if windows decides that it needs to shuffle a thread onto that core for a while then you reduce the speed of the game. By letting windows sort it out it may well shuffle eve off of the original CPU onto the other one to run another thread and then shuffle it back. Morel of the tale, unless there is a specific reason to fiddle with the core assignments just let windows get on with it. ---- God gave us a brain, he also gave us a voice.

K5K AnimalMother Amarr hirr Morsus Mihi	Posted - 2006.12.27 15:53:00 - [23] There is no need. I run three accounts on one box with a single corp processor. All running on the same instance of EvE. Unless you're just bored and wanna play with some settings.

So you don't get low FPS have 1 eve client on each monitor? I had been thinking about this and was actually going to ask. You do and you dont. What you need to do is decide which account is going to be on the 2nd monitor and then launch that account, goto graphics properties and choose the 2nd graphics card in the pull down list. Once that is done it will stutter alot during login but you just drag it onto the 2nd screen and it will speed up again. ---- God gave us a brain, he also gave us a voice.

Gaogan Gallente Solar Storm Axiom Empire	Posted - 2006.12.27 18:27:00 - [25] Originally by: Grez Doesn't matter. Windows will seperate the DX calls and such between the cores. No, it won't. Graphics calls are executed synchronously in the calling thread, so they can not be offloaded to the other cpu while the first continues.

This will be more prevelant on Vista Ultimate as it includes thread optimisation for dual core systems (MS left the optimisation out of lower versions as it only gives at most 1-2% speed improvment). Yes, which can actually give you worse application performance. Basically, by setting thread affinity, you lock your app (Eve in this case) to the processor/core. This means that if Eve needs to do something (say, draw a screen) but the core that it is assigned to is busy (it was preempted by something else - in a multitasking environment, you will always get preempted eventually simply because you use up your timeslice), it won't matter that the other core is sitting idle (doing nothing) at the moment. Eve won't get scheduled on it, it will wait until the core it is assigned to is free (again, even though the other core is not doing anything). This can lead to lower performance in Eve. Basically it's this: People hear that this is what you need to do but have no idea why or what it means and they pass it on as some sort of gospel. Don't listen to those people unless they can also explain when it is good and when it is bad and the ramifications of doing it. Remember, nothing is free and if someone tells you "It just makes it faster" (about anything), take it with a grain of salt and find someone who can explain what it really does. The other test question is to ask what the old patch was and why it worked in older games (why it was recommended in the first place to 'fix' older games on dual core rigs). If they can't answer it, that's a sign. So, the answer to the original question is: You can run multiple Eve clients on any machine you have. Whether or not it will have enough performance for you to do so (to do what you want) is subjective to your own needs. For example, I wouldn't recommend running two pvp clients on a 1.4GHz Athlon with a Geforce4 Ti 4200 video card, but running two mining clients (in high sec) might be doable.

To the point of the question do, let windows deal with it. I run 2-3 clients when I can be bothered to play anymore without lag doing pretty much anything.

Hllaxiu Shiva Morsus Mihi	Posted - 2006.12.29 07:49:00 - [30] The reason to set the affinity on the eve clients is because there was a CTD bug with some builds on dual core processors related to a DX bug. I'm unsure whether this continues to present clients, but I don't seem to have any problems with my conroe... --- Our greatest glory is not in never failing, but in rising up every time we fail. - Emerson
