Grafic card advice needed

[HugePanic]

Hi,

 

my current pc does not show the performance with DCS world AS i would habe expected.

(Running A-10 and BS)

 

CPU i7 960

8GB Ram

Sabertooth x58 main board

Nvidia GTX 460 gratific card

 

Often it goes down to 20 or even 15 fps, especially with many units bomb explosions and so on.

 

I assume the CPU is not limiting, so I am focused on the traffic card here...

 

Does anybbody have an idea of witch grafic card to buy to improve??

This card was only 140€ when I bought it about 1.5years ago...

 

Thanks

well if you want the power cash has to be spent. the 6 series should come down in price if it has not already. try for a 670 if your wallet permits, and if not save up a bit more untill the wallet permits. that way you will get what you actually want. without compromise. (cash has to be the compromise here i am afraid- no other option).

 

this sim deserves it, and demands it. when you simply expereince the sim as intended you`ll be a very happy simmer.

 

ive done the reading at Tom`s hardware and you can expect twice the power if you upgrade to 670 from 470.

The price hasn't dropped by on newegg yet. So if you're planning to get a 670 might as well pay not much more for a 770. Unless your running multimonitor as the available 770s are 2gb cards. With the 700s being a rebrand of the 600s I don't know if a price drop will happen. I was looking for a price drop when the hd7900 came out but the 6900s just sold out. The 700s have just been released so they're not going anywhere if you want to wait to see if the 600s price comes down.

 

What is the CPU clock speed? If its not overclocked that could also be part of the issue.

HugePanic, I just upgraded my GTX 460 to a GTX 670. This was a big improvement for me.

 

Both of these cards were 256-bit memory bus. They run a lot faster than the 128-bit memory bus versions but also cost a lot more...

 

Both of mine were the EVGA versions of the card. There's several vendors that sell these NIVIDIA cards.

 

My old card:

Part Number: 02G-P3-1386-KR

Part Desc: EVGA GeForce GTX 460

Purchased in May 2011.

 

My new card:

Part Number: 02G-P4-2678-KR

Part Desc: EVGA GeForce GTX 670 FTW

Purchased in May 2013.

After reading a few reviews it looks like the 770 is approximately 10% faster than the 680. If you're a fan of amd the 7970 GHz edition performs about the same

Unfortunately none of that really matters much in the realm of DCS. The closer you are to the dirt the worse the performance is gonna be. This is not really resolved no matter how much hardware you throw at it. While a 460 is likely a bottlneck, don't get a 7970 or anything in its immediate price range from AMD or Nvidia if your motivation is solely running DCS. Unless you have money to burn.

whats the budget .... ?

 

gtx660 = ~ $210

gtx660 ti ~ $300

gtx780= ~600

hi,

 

i don´t think the CPU is the problem.

 

It has 4x3.2Ghz, but i can overclock it if it´s necessary.

 

I just did a check run an monitoring the CPU load. It never gets over 40%, most of the time running at 30something %.

 

 

Budget?

If it´s <200€ (260USD) then it is fine. If there is a performance jump spending 320€, i might consider this also...

 

I just found that reducing the instrument resoltion at the options (512) brings about 10FPS.....

anyhow, i want´to change something...

 

I only have performance issues with DCS, everything else doesn´t matter or is running nicely...

 

Thanks for all your comments, i will do some checkes on the cards recomendet by hypersonik this evening....

$300 usd would put you in the hd7950 or 660ti. Which is where I generally recommend. Between 200 and 250 would be the 650ti or hd7800 series. Which for aaa games may be on the weak side. The 760ti should be out soon I'm guessing around the same price as the 660ti. You should be able to google gpu reviews and get a good comparison of the various gpus.

 

CPU clock has a lot to do with dcs performance as quite alot in dcs is processed by the CPU. It also only uses two core which is why your CPU usage is showing 30%-40%. One core is fully loaded, one is ~20-30% loaded the other two are near idle. If you do over clock you need a good CPU cooler. Not a factory cooler.I use a hyper 212 evo as it got decent reviews and didn't break the bank.

 

Reading the forums some people report significant change with fps while some report minor change with gpu upgrade. I would like to say I got maybe 10-15 fps going from 260ti to 6950 but a 260ti is on the very weak side for dcs.

In general I would recommend Nvidia, simply by the fact that SLI works without a hitch.

 

I have had 2x GTX 580 in SLI, and now running 2x GTX Titan in SLI, and in both occasions the SLI is working without a problem.

[sslechta]

Hey Tzeer. Nice to hear from you. Liked your graphics testing thread. One test I thought about trying not sure if it's been done......

 

I would take my old 460 card and force it in NVIDIA settings to be PHYSX only. I saw a few threads in here talking about PHYSX in the past and it sounds like no benefit really in DCS. I wonder if forcing that card to PHYSX only would free up the new 670 card more.

 

I could monitor FPS on the 670 to see if it improves anything before to after.

 

Thoughts?

[TZeer]

Thanks :)

 

Don't think it will have any effect. DCS has no support for PHYSX, so your primary GPU will be the one working with DCS.

 

I would set your 460 to physx only, as there is no way for those two cards to work together at the same time in any other way, like SLI for example.

[Bee_Sting]

Great idea! You will see better performance in BF3 by doing this. I would do the same thing. DCS games are a different beast.

[blkspade]

Should probably also ask what resolution you'd be playing at, and what if any other games do you play. I got the 7970 mostly to drive the 2560x1440 monitor I have for DCS/FC3 a few other games and GPGPU stuff I'm into. It does handle DCS:W well enough at that resolution, but you still have to make some compromises in the graphic settings.

[Bee_Sting]

People please keep in mind that DCS games are mostly cpu driven and by saying this keep you graphics settings to meduim or set them to your system's best performance. DCS World is a very big and it takes alot of rendering this is what causes low fraps when playing at high res and multiscreen setups. If you are going to get any card make sure you have atleast 2gbits of ram on your card.

Sorry for crashing the thread but I have a question that you guys may be able to answer.

 

My setup is one GTX560 1.5GB and one GTX680 4GB. I have in the past been running three monitors but have now tried 5 monitor. No matter what I try I can only get one of the card to take the load even though monitors are connected to both. I have tried running with and without Nvidia Surround. It seems like the graphics card having the main monitor is the only card to get load.

 

Is there any use of the GTX560 card at all besides supplying additional connections to the monitors?

 

Any advice is more than welcome :music_whistling:

 

Cheers

Hans

Hello all, I am the process of choosing a new graphics card. I currently have a GTX 295 which seemed to be ok for DCS but the new U1-H1 Huey is kinda choppy.(forgive the pun). I have about a grand to spend and I am looking at the GTX 690. It is about even with two GTX 680's in SLI. The Titan looked interesting as I also do some work in 3DS MAX. But from what I read, the Titan's drivers are not optimized for engineering apps like the higher end Tesla cards. To the guy who was running two Titan's in SLI, do you do any 3d animation and if so, how does the Titan perform? I only game with a single 1920x1200 monitor, but might like to try 3 way surround in the future. The Titan's 6 Gb of Vram looks really good, but the 690 beats it in all the gaming comparisons. I look foward to seeing any suggestions.
