bottlenecks

[nejc311]

I have an old computer that I intend to upgrade in the future.

 

my current specs:

 

i7-980x @4.48GHz

6GB DDR3 @ 1600MHz cl6

GTX 580 @ 2.0 x16

 

after upgrade:

 

i7-980x @ 4.48GHz

12GB DDR3 @ 1866 cl9 (or maybe 12GB @ 2000Mhz cl8 )

2 x GTX 980 @ 2.0 x16 x16

 

 

Having simming with rift CV1 in DCS at the highest settings in mind, would this be a worthy upgrade? Or is the cpu and/or ram and/or 2.0 PCIe slot too slow and would bottleneck the GPUs?

 

Any help would be appreciated.

I have seen good results using the xeon 1366 chips so yours would be about the same. I would say upgrade to a single 980 and see what that gets you. What resolution are you planning on running?

[nejc311]

I see. Although I'm fine with 1080p on monitor, I read that for CV1 you'll need a decent 4k gaming machine because of expected high resolution and refresh rate on that thing. Which is why I'm worried.

I think you are fine, granted you have a SSD in there as well.

Just pray nvidia has the vr sli tech out by then lol

I have an SSD but I thought they only affect loading times.

 

 

I'm just worried as I see so manny people here have newer CPUs at higher speeds especially when you want to go at maxed setting in vr resolution and refresh rate.

 

I was planing on waiting till EDGE and CV1 but my GPU died and will probably have to upgrade prematurely as waiting without a GPU till those two get released might take eons.

SSD will only affect loading times.

 

Overclocking your CPU will be the big benefit at this time. I understand EDGE will support multicore processors. At that time, OC may not be necessary.

Yes. It is overclocked to 4.48 from 3.33.

 

Edge will not support multi core. Just improvements for multi GPU. link

[Gladman]

I think your confusing multi core with multi threading.

Oh. So they are working on multicore? They're not mentioning it. Seems like a big thing to not mention in that post. Are you sure?

To be honest, I can't find the thread that I thought stated it. The basic idea was that it had future potential but at this time was only allowing minimal advances.

I don't know that its really that big a thing, with DX11 being used the GPU's will be the higher priority, I would think. The more prevalent CPU's clock speeds and OC ability is what would be the performance enhancer on that end.

Oddly enough, with DCS today, I personally see better performance from my CPU OC than my GPU.

It still seems a bit weird to me. How can an application support multy-core but not hyper-threading or vice versa. I'd think that programmatically they're equivalent. With hyper-threading on, my system has 12 logical cores. With hyper-threading off, it has 6 logical cores or threads. I'm not sure whether the programs even distinguish.

 

I did read somewhere though that the load will be put off somewhat from the CPU onto the GPU with EDGE.

[Gladman]

I think its because the program only uses a couple of cores so if it uses more than one core it is multi core but given it won't use the 7-12 core brought in by the use of hyperthreading, the tech is null.

Best quess.

DCS is a single thread , with audio offloaded to another thread. This is not planned to be changed with 2.0
