How does Ryzen perform in VR?

Well, I'm building a new rig, and just not sure which direction to go. Running a 4770k @4.6ghz right now and a GTX 1070. I don't have many issues with elite in VR, but I'd definitely like to crank the settings up higher.

I'm just wondering if anyone has a 2700x. I'm debating that or an 8700k and a 1080ti (2000 series is way overpriced). I'd like to try out AMD for something different, but I know single threaded performance still matters.

Does anyone play ED in VR with Ryzen? I'd love to hear your thoughts

Eh, cpu seems to matter a lot when it comes to minimum frames. The 2700x and 8700k will be huge upgrades in that department. Just debating between the two.

It's beautiful. Overall, the 2700x is better for price per performance. If you overclock it you can get decent single core performance. I have mine overclocked to 4.3 ghz with 3466 mhz memory. You'll have to water cool for that performance, of course. And my 1080ti is overclocked to 2100 mhz as well. And yes, it is water cooled.

And with zen 2 coming out next year, all you have to do is upgrade the chip and keep the same motherboard.

I so far can't put my finger on it but Ryzen or AMD owners seem to have more latency issues in VR than with Intel builds.
Althoigh i havent touched a recent amd system with VR so that's just a hunch I get from threads here and other places, could also just be it needs better tuning.

What I do know for certain is that my 1080ti was being heavily throttled by my i7 4790k and upgrading to an i7 8700k was a massive upgrade.
But that also meant new mobo, new SSD and M.2 drive and ddr4 ram etc.
Can't attribute it all to just cpu.

As for VR cpu's the new i9 9900k is naturally the top monster in both multithreaded and single threaded tasks.

Personally I don't really see much point in upgrading from the 8700k, I'm already clearly being limited by my GPU in VR.
And quite frankly the 2080ti is far to expensive and not enough performance increase either.

My current hypothesis is CPU demand is a function of the fps itself.
With the new HMD's coming frame rate will remain the same but resolution will increase and that is squarely a GPU task.

And once you have a cpu able to handle the fps generation the rest is on you, and you won't see much benefit getting a bigger cpu.
That's at least how I convince myself to not get the i9 ;)

That's pretty much what I think too. I recently upgraded to the i7 8700K after much toying with getting a Ryzen 1700X (it was just before the 2nd gen came out) and concluded that the intel was the best choice for me. All the benchmarks I saw showed that i7 could produce higher frame rates than Ryzen and VR probably translates as 180 FPS gaming more than anything else. I don't stream or anything like that and my upgrade was purely to get a better VR experience. Coming from an i5 4670K it was a stunning improvement and seemed more like I'd dropped in a way more powerful GPU. Very happy with my choice.


The only thing that still bottlenecks the CPU in VR is X plane 11 but that should resolve itself when they switch from open GL to Vulkan. I don't think I'd get any benefit from a 9900K and if faced with the choice between a 8700K and a 2700K I'd probably go the same way again. My only reservation is that the AMD board with be compatible with the next gen Ryzen which is going to 7nm and may take the lead in gaming since they closed the gap a fair bit with the 2700X. That said buying a chip now and replacing it in a year with a newer model is an expensive strategy; then again the cost of the i7 has gone up about £100 since I bought mine!!

If money was no object then I’d certainly go for a 9900K with an epic cooling solution... apparently they get a bit toasty lol

Same with DCS, it's loads onto one or at most two threads and that's it and can't get beyond 75 ish fps regardless of settings most places.
It's much better to just lock to ASW and add a couple of notches to SS.

But that's cause they seem to be doing things the same way as things where nearly a decade ago.

Now ED (Eagle Dynamics) is also working on moving over to Vulkan, most likely a 2019 release but that's just guessing.
And this for instance would enable a lot of SMP use, and I think they intend to use Vulkan in a manner that allows them to run the graphics rendering seperate from the physics simulation something that can have great benefits for VR.

I don't think AMD is bad or anything and I'm sure there are many out there who enjoy VR with them.

Yeah I am stuck at 45FPS with ASW in X plane which in some ways adds to the realism.... it makes air sick :D

I don’t think the Ryzen chips are bad either, they are certainly better value for money. I actually wanted AMD to win in my decision as it’s great they have stuffed it to intel.

If you overclock your Ryzen you can get decent single core performance.

And I found a pretty neat software that can configure your processes core affinity, priority, I/O priority, etc...
It's called "Process Lasso".

Try it! You'll like it.

Thanks for the info. The 9900k isn't an option, as it is a horrible value. Probably gonna look at used Intel and AMD options and grab the best bang for the buck that comes around.

With a Ryzen 1 or 2 series you just have to make sure the RAM is 3200 or faster with low CAS latency, then the overall latency of the CPU is top notch for maintaining FPS under thread heavy workloads and high resolutions. For the top Intels it is not too dramatic when going lower RAM speeds because the internal CPU latency isn't fixed to the RAM speed grade.

Get a 6 core for ED in VR at least, but better 8 cores in the long run. The Ryzen AM4 socket will very likely get a superior upgrade option next summer, so i'd get a good mainboard with extra power connectors for the CPU just in case it's needed for a cheapo 5GHz upgrade next year. But the GPU is the main bottleneck usually...

I do now, have you bought already Droogie?

Starting a new system build I got a 1080ti which got used on 1440 vr with a 1st/2nd gen i5 with 4 cores and no hyper threading. The experience was good for me although ASW was running most of the time and it was clear the processor was a bottleneck.

Decided to go with AMD for a new processor I got a decent motherboard and overclockable 3200mhz ram with low latency but decided to get a lower end processor with more cores and the intention of moving to Ryzen 3 when it appears next year. Thing is I probably don't need to now.
With a 1600 overclocked to 3800mhz using the spire cooler the processor is no longer the bottle neck and rarely goes over 75% usage while I'm on a fairly steady 90fps.

Maybe a faster /more expensive processor will get me a few extra frames but for me a lowly ryzen 1600 is doing the job.

Hello,

I just done it, went from a i7 4770k to a ryzen 2700x.
Graphic card is 1070.

Elite on Oculus works fine on both computers. However, ingame, I get a (very) little more framerate with the new Ryzen.

As a workstation, multithreading (8 cores) is really more powerful, but ingame, it's just a little bit better (its the graphic card which makes the framerate, not the CPU).

So no NEED to change, but as for VR, but if you go from a 4770k to a 2700x you will gain a little.

About 4 months ago I went from a 3930k @ 5ghz to a Ryzen 2700.

While I agree that it wasn't a significant jump in maximum frames, the minimum frames were a significant improvement. Overall it's a much smoother experience and I did find I could then bump up some settings a bit.

e.g. with the CPU upgrade I was able to go from 1.25 HMD IQ to 1.50 with my Vive Pro and maintain a smooth experience.

I didn't particularly upgrade for gaming purposes so this is a bonus to me.

Now as someone mentioned earlier, I did see a noticable improvement in latency for VR by changing my RAM timings from 3200mhz CL16 to 3200mhz CL14, ~15% boost in VR latency performance.

I went from a 5ghz+ 7700k to a Ryzen 1700 and now a 2600x. No regrets. Would do it again. I'll will be upgrading to whatever 8 core Ryzen chip can do 5ghz.

IMO, if you're on any kind of budget, there is zero reason to buy Intel these days. They are way over priced and run hotter compared to AMD. You can easily save $150 to $200 on CPU and mobo; money which would be better off going towards a better GPU as it will net you way more frames than going with an Intel CPU.
