VR Specs Question

[ACG_pezman]

Hey guys,

 

So it's been a while since I flew because I came into a VR headset and gave it a shot.  It was truly amazing and sickening (couldn't keep 45fps), and I realized I couldn't fly this game anymore unless it was in VR.  So it's been about a year and half but I'm getting ready to get back into the game - problem is I can't decide on what CPU to purchase for VR and this game:

 

i7 9700k or i7 8700k or i5 9600k? 

 

Single core is where it's at, and the 8700k has six cores, twelve threads - but I read that hyperthreading isn't good for VR and this game - so then the 9700k with eight cores and eight threads looks like the better option, but then the i5 9600k is also six cores (two more than my current 4690k at 4.5Ghz) which, with my new Gigabyte 1070 G1 (thing is better than a 1070ti), I can maintain 45fps pretty well in all cases - except close to the ground.

 

Question is, I dont know which CPU will be the better choice for this game and yeild me more raw performance.  Just got my tax return so I'm thinking of swinging that 9700k - but is it really any better than the 8700k?

 

thanks guys,

9700k is marginally better (~5-8%) than the 8700k, however it's a 'next gen' cpu, hence if you get it then your setup will be future proof. But if you have an older gen motherboard (i.e. 370) then I'd go with 8700k.  It's a question of value, really... performance wise these 2 are the same.

 

can't speak to 9600k at all though..

You won't go wrong with the 9700k, it would do quite well.

I am rocking an i9 9900k @ 5.1 GHz on a Z390 Motherboard and my fps run from 85-90 fps.

You think I could do decent with my 1070G1?

 

Memory Clock:  8008Mhz

Core Clock:  1823Mhz

Everything else (bus speed, ram size, etc.) is the same as all other nvidia cards in the same class.

 

Also, does the DDR4 RAM speed matter much?  2400Mhz vs 3000 or 3200Mhz?  And I e read the 9700k and 9900k run hot at stock speeds, so water cooling is almost a must with them - especially if you’re gonna OC which I’m sure for us is compulsory now.

 

Thanks

can't speak to 1070's performance, I have 1080TI and it's not super stellar.

 

But your second question about DRAM speed:  yes, RAM speed absolutely matters to the performance of the CPU. Both go together hand in hand. Without fast RAM the CPU will lag in performance, regardless of its OC state.  The advice is to get 3200MHZ RAM with 14 CAS latency (no more).

I think the 9600K is fine for IL2, 6 cores, you can probably get it up to 4.9 or 5.0ghz with good liquid cooling. And it saves you a packet over the 8700K or 9700K, which you can put towards better RAM or (eventually) GPU. I upgraded from a 1070 as it wasn't quite enough for IL2, I'd say a 1080 is really the sweet spot. I have a 2080 now and am happy with it, but a 2070 I think would do pretty well also.

8600k at 4.5ghz, 3600mhz RAM (CAS 17) and a GTX1080G1 and I have no issues with the Rift, any time I flip it up to look at the fps it's doing 90.

Not sure on that because I do have an GTX1080 and always measuring by using the fpsVR tool, so I can see what is bottlenecking. I think despite I have overclocked the GTX1080, it is for VR on the low side or you are satisfy by generating low quality. I would go for the next gen. RTX2080 minimum and for IL2 future proof or maybe the new Vega7.

Fully agreed.

 

For CPU, the most important point is how far you can go with overclocking. If your CPU is able to reach 5.2 you are the king. Just only thinking about Il-2 right now, the best price-wise option is i5-9600K and a good liquid cooling.

 

For GPU it depends on the VR headset and the SS you will use (and some in game graphics settings). If you have the Rift and use SS around 130% (SteamVR) then a 1070 is quite OK. If you then have a 1080 then you can go up to 160% or so. For the Rift, there is definitely no need to go higher than 1080.

 

You have to know that even a 9900K at 5.0GHz with 2080Ti is not able to have 90 fps ALL the time. But it really doesn't matter to much.
