The best CPU for flying with the VR headset

Recommended Posts

Hello,

I currently have an i5 6600K (that I can't overclock because when I purchased my MOBO, I took a MSI H170 Gaming M3, and with this one, no OC, so I'm stuck with 3,50 ghz, and I think that it's not enought for the VR because sometimes it's realy hard for me on P3D or XP11 to get the 30 FPS ad have something confortable if I want good graphisme

So, I though about buying an i7 7700k (with 4,2 ghz stock), is it worth the upgrade? Will the perf be really better with this CPU??

 

Regards

Have you tried running the steamvr performance test to see where your current CPU sits? http://store.steampowered.com/app/323910/SteamVR_Performance_Test/

Absolutely not, I'll try, thank you for the idea

We are weeks away from the release of the 8700k. That is the one Ill be getting! Buying a 7700k now seems a little bit puzzling.

And what will be the perf of this one vs a i5 6600K Will I gain lot of power / FPS?

Well everything indicates that the 8700k will have better IPC performance than the i7700k (around 10%) and also 2 extra cores to reduce the load on the main core for parallel activities. While singe core performance is still king for gaming/simulation/VR, having more than four core should be something that becomes more relevant sooner than later.

I was ready to jump for a new i7 7700k and a 1080ti, your comment delayed the take off. Guess waiting a few weeks till 8700k is released won´t hurt too much.

Thanks tgcbraun!!

 

Cheers

Sorry guys - but don't ya just love a typo now and then?

I can almost smell the molten bakelite already..... :biggrin:

I wonder if LM will re write the simulator code to make use of all the cores in the new 8700?

As CPU architecture leaps ahead, our flight simulators appear somewhat stuck in the past.

The CPU/GPU market seems fixated on "Games"....but we want our flight simulators to look as good too!

For me its all about the bang for buck. If money is no option, you may want to wait for the 8700... but then again what real life performance gain (in a VR flight sim ) does the 8700 bring over anything else... does anyone know yet? 

The original poster has not mentioned which graphics card he has. Depending on that, it could be a more worthy upgrade to change the GPU?

I think its always dangerous to start making recommendations without a holistic view of spec, budget and exacting sim needs.

 

Also, the bottom line is always...

                                                    wait until xxxx, there is something better coming out.

My cpu is only slightly faster, at 3.6 GHZ/7700, and I get way better performance in P3d and XP11.  My graphics card is a 1060, that may be a factor in the OP's performance.  I do scale down AI in P3d, but I haven't compromised on the other slider settings.  I have 8GB system ram and Win 10.

Well I can say I went from a 980 to a 1080 and the performance jump was massive (in VR)

Separately I went from a i5 to an i7 and the difference was small (in VR)

VR is different from flat screen sim, its all about the GPU.

Most of our legacy sims are seriously CPU-dependant, and as a general rule there's little to be done about it. Even the latest Cpu's won't change the fps much from a well overclocked predecessor.....

For things that are more gpu dependant, like modern games using vr, a better gpu will definitely help though.

I know when I switched to a better cpu and a 1080 ti, pretty much nothing notable happened in FSX, and not much more in P3D. X-plane got a noticeable bump, and Aerofly went to lightspeed.

DCS 2.0 also responded nicely.

I've got a GTX 1070, so I think that the best upgrade I can do is the CPU

What did the Steam VR tool say about your setup?

I have a GTX 1060 and I am getting great performance, but I don't know how much VR adds to that.  Since it expands what you see, the rendering will take longer, probably halving your fps.  It's a tipping point between CPU speed and GPU speed, and of course RAM makes a big difference, the more, the better to hold those textures.  RAM should be greater than 2GB on the graphics card, and at least 8GB on your main system.  The sims need RAM, they will take as much as you have.  When my old system started to fail, half my RAM slots died so I went from 8GB to 4GB.  I noticed an immediate difference in the sim, blurries came back and I had to live with it until I got my new system.  Only FS9 worked well, with its lower texture resolution.  FSX stuttered alot although it was workable.  So keep RAM in mind when you are making your decisions.  The more RAM, the smoother the sim flows.

Hi

Interestingly I ran the VR steam performance test. It gave me a quality score of very high

and said my system was performing well above recommended VR requirements.

Note I only have an old Sandybridge O/C at 4.6ghz and 8gb of RAM

my graphics card is a 1080gtx however

With specs like that I would expect no problem.  I would run with just 4x AA though, anything to lower stress on the gpu, even lower if you have to.  Your specs soar above mine, yet I get good performance in a non-VR P3d environment.  I run at 3.6 GHZ and have a 1060gtx.  The only add-on that struggles seems to be the Carenado Premier 1, I get good performance with all other add-ons and if you visit the screenshots forum, you'll see good rendering both in P3d and Xp11.  With those shots, my fps is locked at 33fps.  My experience is quite smooth, with autogen in Xp11 and minus autogen in P3d.

I run a TV at 4K resolution and the FSL A320 so quite taxing for an old system. As you say I expect to run VR okay with this system, I think the

hardware challenges will be when VR goes to the higher resolutions

Don't be afraid to lower your texture resolution to 2048x2048 if you haven't already done so.  My latest screenshots show what it looks like, I felt there was no real harm since my monitor only supports the 2K resolution.  A higher res monitor might show the difference, but when I fly in real life, 2K is about what I perceive anyway at my age.  Never bothered me when flying IRL, my instructor said I could always spot traffic before he could, since my vision is about 20x10 at a distance.

Here's a question for the gurus: Does the resolution that XP is displayed at on the parent monitor affect the displayed output in the Oculus HDM I wonder? Although displaying through a reduced 'Window' on my monitor (using FlyInside), do I actually need to run XP at my native monitor res of 2560x1440 since I am actually viewing XP in VR anyway?

As a general rule, the resolution in the headset and on the monitor have nothing to do with one another. In fact, it's better to save some system resources by turning the monitor to the tiniest windowed resolution you can get away with.

You might notice that while using Flyinside, the resolution you set in the program can enable supersampling in the headset but does nothing for your monitor.

I'm not quite sure of the relationship using the funky P3D native Vr mode, however.
