Multiboxing Hardware Science!

[MiRai]

Thanks for the work Fen, seems like grabbing a 3Gb 580 is the go for now and hold off on SLI until we see how a single handles RAGE, BF3, Skyrim etc later in the year.

SLI did immediately give a noticeable boost in both TERA Online and Civilization V completely maxed out so it
isn't a complete loss but, I'm still not entirely sure I can justify the $600 price tag of this second card. I keep
telling myself just give it a few weeks but... I have a feeling this card is going back and I'll just eat the
restocking fee.

SLI did help with boxing rift right ? A lot of new games had problems supporting it at launch (just look at Crysis 2, the once benchmark hardcore PC game doesn't support SLI at a launch, GG).


but I would need a new PSU first.


Another mistake that I made with my current built, (other than purchasing a GTX 295 lol) is to go with a mediocre power supply. The PSU does degrade over time. It is slowly dying. and I had this constant problem of rebooting my PC automatically when I try to push the graphics. Damn you "witcher 2"~. as soon as I do anything in that game, it reboots.

longer than 2 hrs of rift, reboots. I first thought it was software crash or my card was overheating. But more and more, I think it was due to the PSU as how can the card overheat when I am just 5 seconds into the game. It was at 50 degree to start with. Insufficient power/unstable current seems to be the cause.


on a side note,
Speaking of upgrading hardware, have you guys noticed those "rent a gaming PC/or graphic cards services"? With the frequency that we are upgrading, maybe it will be worth while just to rent cards/PCs than buy them. 2k for 2 years, that's like 84 dollar every month.

Yeah, looking at costs now that my tax has been done.

Looking at benches and your results here I'm wondering if a 2Gb 560Ti would be just as effective for 5-boxing as a 3Gb 580. Looking at $319 vs $609 I'm not sure if it's worth it atm or in the long-run if I look to move to Ivy Bridge next year when I'm assuming the 6xx's will be out.

There's also something like the 2.5GB 570 that falls in between (even though I personally don't like those fan designs).

4 DK's in starting area under DX11 = 994Mb usage with some artifacting starting on a 1Gb card
Same 4 in same spot with same settings under DX9 = 667 Mb usage

I guess there is no way to know if wow or win7 uses the extra video ram for cacheing. Probably not ....

Looks like then for up to 7 boxing 2G ram will do the job for sure, even with DX11.

I got bored last night so I thought I'd see how far I could push my hardware.











All windows are rendering at 1920x1080 with instant swapping enabled. Even with 30 screens there is zero
lag while swapping between any of them. Main @ 60FPS / Slaves @ 10 FPS. I would advise against taking
these 30 characters into a major city anywhere near peak times as you can see my system RAM is almost
maxed out.

I split the GPU load between my video cards and they are rendering 15 clients each. As you can see I could
have put all 30 on a single card and I would have still been way under the 3GB limit. This is of course using
DX9 since DX11 would have most likely maxed out the VRAM. If your interest is to box as many characters
as you can on a single machine it's unlikely that you care how high your video settings are anyway.

I would say running 20 on a single machine would allow you the system RAM headroom you would need to
visit major cities and PvP with; although, it would still be cutting it close during intense situations.

That's hysterical.

I upgraded to a 3GB 580 a week ago. I had a problem with one of the RAID 1 drives where I keep my data and figured that if I was going to pop open the case to install a new hard drive, I may as well fulfill a few dreams.

Humm so 15 clients don't even take up 1G of video card ram ...


How do you say you render 15 clients per card, there seems only one screen, are they tiled on the 2nd screen?

If they are not tiled they are not being rendered (although there are 15 clients per card) to my way of thinking. Or if they are all in the background not visible they are also not being rendered. If that is the case your fast swaping times is just because the 580 can redraw a new screen faster then your fps. The fact you have 10fps in background would tend to indicate that you are not gaining anything by tiling in full resolution. Your card is fast enough to render a full screen in less then 1/60th of a second. Which I think should give you instant swaping no matter what.

I wonder what would be the result if you were in different zones, does the card use so little Video Ram because its able to share data between the 15 clients? How does the ram go up from when you load 1 to many is the first load a lot lot bigger then 950/15? If it is then the video ram is being shared between clients. Or does each client just take 60MB of ram?

So it takes 30 clients to use up 16G of system ram. More good infos.

Good testing for sure though.

Do you think you can 15 box on your system (with just one 3G card) with no trouble in populated areas?
