Best GPU/CPU for DCS


Recommended Posts

Hi Folks

I'm thinking about to get back into military flight simulations after a long time. Long time ago I enjoyed Falcon 4 (BMS and Allied Force)on a high level. Now I'm looking for optimum Hardware, especially for an output on a WHD Monitor 2560x1080 or even on WQHD 3440x1440. What do you think about this Choice:

  • AMD 5900x
  • AMD 6750XT 12 GB
  • 64 GB RAM
  • Mainboard X570 or B550
  • 1 TB SSD R/W: 7000/5000

Does anybody know it would have a significant performance decrease if I'd use an 5800x instead of an 5900x?

I'd like to simulate in high fidelity avionic-settings and with best possible Framerates with high graphics-quality, must not be the highest, but good enough especially to fly with the F-16.

Does anybody have experience with a HW-setting comparable to this?

I don't think you will see a difference between 5900X and 5800X, maybe the 5800X3D with the right GPU will yield more performance, apropos GPU, I would pick a bigger GPU, rather a 5800X + 6800XT than 5900X and a 6750XT.

64GB is correct.

If building am AMD system right now, I'd say 5800X3D over a 5800 or a 5900. The 6750XT is plenty of muscle outside of VR.

That being said, AM4 is a dead end platform so when you upgrade it will have to be a new motherboard and CPU. However, 5800X3D will easily hold you over for a couple of years (unless you need DDR5 and PCIE 5 right now).

I'm not on a hunt for the last FPS and VR ist not an option for me, I just want to fly seriously and just without annoying stuttering or FPS-Drops, if possible.

On Youtube I saw vids with breathtaking recordings with older CPU and former "high-end" 2080ti or 2070 - So I  think, and hope, that a 6750 should be more than ok.

Thank you guys, but I will stay a while tuned here, maybe for more experience!?

Basically what Bitmaster said. You could go with a 5600x CPU then pump as much as you can into a GPU. If you want to use a resolution at 3440x1440. You really want a AMD 6800xt or Nvidia 3080-3030ti. Have a search on Youtube for video's by "PointBlank". 

As for the CPU something like a 5600x or and Intel 12600k using DDR4 would be just fine for DCS. For the Dram I would recommend 64gb at a speed of 3200Mhz C16 or 3600Mhz C18, seriously both are just fine.

Right now, DCS is CPU all the way, and poorly optimized.

Go LGA1700 Intel for sure right now. If you buy AM4 stuff, it will be obsolete by July.

TBH, an i5 12600 would be a good CPU. I went SFF so was "shoe horned" into DDR5, that's the future anyways! $$

DCS loves memory, to run heavy MP servers, you'll need 64GB. I wish GN and Jayz2cents played DCS sometimes!

 

GPU.. Same as Star Citizen if you can, VRAM is everything, until the engine gets optimized..

This question comes at just the right time for me as I just ordered a ReverbG2 yesterday.
I currently have an i9-9900k (not overclocked) 64GB RAM and a Vega 64 Sapphire Nitro+ installed in my PC.
I could upgrade the CPU to a 5800x if that would help, but I'm still unsure whether to go with Nvidia or AMD and whether to wait a few months for the new GPUs. I mainly want to play DCS and MSFS2020.

I am currently using a ryzen 5 1600 and would like to upgrade to a ryzen 5 5600. For me, of course, the question arises: Do you notice this difference in DCS World? Is this investment worth it? Has anyone had any experience with this? On my current computer, DCS runs on an M.2 hard drive, 48 GB DDR 4 and an Nvidia 2070 GraKa are used. I set the screen resolution to 2560x1440. VR doesn't matter to me. Since I want to invest as little money as possible in the upgrade and the ryzen 5 5600 is currently very cheap, I thought it would be a good investment. And I don't want to switch to Intel either. And don't switch to Ryzen 7 or Ryzen 9 either.

I would like to thank you in advance for the factual, professional answers.

For a regular screen my 8700k and 1080ti was perfectly fine to run at 100-120fps. 

So for what OP has posted should be more than excellent for anything below 4k imo.

 

As for a G2 things get expensive fast...

My 1080ti certainly wasn't feeding that acceptably, unless I would run the g2 at 40% resolution, and the 8700k would bottleneck possibly even a 3070, VR DCS also really likes VRAM, but from everything I hear AMD gpu's still has performance "issues" compared to team green, this is just hearsay and can probably vary greatly between builds and what people consider acceptable.

ATM I am running a 3090, (only thing I was lucky to find available a year ago), a 12700k and 64GB ram.

The step from the 8700k to the 12700, halved if not, more my cpu frametimes in VR, basically from 16-8ms with peaks at 12-14 instead of 30ms, it is still DCS so spikes do happen.

@kotor633 A move from a Ryzen 1600 to a 5600 would be huge I am sure, not only 800mhz faster it has twice the L3 cache and dare I say double the IPC, so it does about twice the work per clock.

A Combo with a cheaper CPU  but a better GPU seems really to be a better decision, and my budget won't explode. The higher the resolution, more less the CPU has to do.

Here a Test with Cyberpunk, without Raytracing. It's not DCS but the Resolution I'd like to use and maybe comparable:

My combo now may will be this:

  • i5 11600k 
  • Z590 Board with PCI-E 4.0
  • 6800 XT
  • 64 GB

HI Ironman,

It is a shared opinion and I observed this comparing directly myself. While there is nothing wrong with AMD cards at all! They have a 256 bit memory bus! The bigger Nvidia 30 series cards cope with resolutions above 2560x1440 a lot lot better, especially if your flying down low. 

This only applies to DCS, so if your going for 3440x1440. Just take a deep dive into Nvidia vs AMD at high resolutions in DCS. Especially if you like smooth graphics performance at 60fps and above.

Looking at data for other games as a guide to DCS is not relevant, I know. I did the same thing, built my system and thought, oh dear.....bummer! To avoid any let down please check.

Well, this only makes sense if you buy DDR5-RAM that you cannot buy yet. I am not aware of fast DDR5 kits with 64GB ( 2x32GB ) as we know that they perform terribly with 4 modules.

It makes no sense to buy 64GB 4800MHz for a hell of money and also get the slower CPU vs. the 5800X3D.

 

I would buy into AMD, a 5800X3D and 64GB of low latency 3200-3600MHz RAM, saves a ton of money and will likely perform the same, I dare to say even better.

Get at least a 1TB drive for DCS alone, a 512GB is already maxed out, my install is 403GB with all maps and most but not all modules. If I had all modules I would certainly cross the 500GB marker.

Well. 
Thanks for the answer, but...
The RAM I currently have is (Kingston 64GB DDR5 5200MHz Kit(2x32GB)), if there will be faster ones I will change it.
I don't buy AMD processors (I had the "privilege" earlier, and Radeon GPUs too), I prefer Intel.

Well then,

sure, it's the Top Dog from Intel, you cannot get much faster anyway, even with a 5800X3D CPU.

Make sure you get a decent cooler and check the mating, the 12th series' Achilles' tendon.

Have fun 😉

If you do mostly gaming and have the right GPU to make use of it...I would !

@BitMaster and generell. I am planing to upgrade from my 6700k.
What you guys think about 12700k vs 5800X3D? combined with a RTX 3080. 
Is the cache from 5800X3D very usefull in dcs?
I have to say i am more into intel as i was not happy with my last AMD cpu, but looks like times have changed. (it was a FX8350)

I know about the AM4 is dead soon, but i want keep my DDR4. So AM5 is no question to me.

So i am thinking about 12600k (20mb cache) / 12700k (25mb cache) / 5800X3D (96mb cache) OR wait for the new 13700k (cache?)

Also i heard that the new raptor lake cpu get more cache and will also support on Z690 Mainboards is there any reason why it is heavy recommended to go with Z790 Boards?

For the 12700K i would go for this Mainboard (MSI MAG Z690 Tomahawk WIFI DDR4). This good?

PSU i would go for this. Fractal Design Ion Gold 850W ATX 2.52 90€ (friend using it with rtx 3090+12900k) or be quiet! Straight Power 11 Platinum 850W ATX 2.51 141€

If Raptor Lake comming in christmas time i dont know if i want wait that long. If going for Alder Lake i could sell CPU later and upgrade raptor lake maybe.

But still the question.
Does the 5800X3D perfrom much better in DCS vs the 12700k? I play mostly big multiplayer servers.

greets and sry my english

Personally, there's not a gigantic difference between performance these days like a few gen ago. I have a 6700k now and used to use a 8350FX as you did. With Intel you know they're going to use a different socket every time to force you buy a new motherboard, with AMD you'll probably have the option of at least a few upgrades of reusability out of a given motherboard, which imo is more helpful these days.

I'll be doing my own upgrade later this year as the supply issues seem to be easing. I plan on doing a full rebuild, though, as it's been 6+ years for me, so I'm thinking probably AMD cpu, 4080/or whatever they end up calling it, and 64gb of either DDR4/5 depending on prices. That should also bump my performance up to finally properly make use of the G2 I have (on that note, if anybody wants a Rift S in the US&A, hit me up)

Just stumbled on this thread when doing a search.  My youngest son (16) is looking to get a PC, so I was going to upgrade my system a bit (5600X/3070) and hand mine down to my older son (3060ti/3600), then he hands his down to the youngest.  The sensible option seems to be getting a 5800X3D and a 4070 or 3080 12GB (if the prices get realistic), but I don't think the CPU upgrade makes any sense as we all play at 1440p:

It seems the same scaling rules apply with modern CPU's when you play above 1080p, unless you have a really old 1600 or quad core Intel or something.  Not a 'lot' of benefit at 1440p/4K, although the RiftBreaker results are interesting.  It looks to make sense just to let the older son buy a 5600 and stick with what I have does it not?  I'm not into wasting money just to play games (yes, I can 'afford it', so spare me), and I play other games than just DCS.  Thoughts?  Does anyone have any real-world, actual data to support that DCS performs better with a 5800X3D vs a 5600X?  I don't care about VR.  The line that 'it's more expensive, and the theoretical specs prove it's better in DCS' is not 'data'.

Hey guys, since this is over a year old and I am intending to upgrade from a 5900X, what is currently the best CPU for DCS? GPU is a 4090. Is it a 7900/7950X3D or Intel's top dog? Should I wait for the 14 series of Intel? Generally, I prefer Intel for my next rig, since AMD did not convince me platform wise (crappy USB implementation, even now after all these updates to the USB my G2 is not totally perfect and I have crackling from my USB-C Audio Interface which I use as a soundcard). However, if the X3D-CPUs are significantly faster, I would go with AMD another time.
