anyone tested the Intel Core i7 5820K 6x 3.30GHz So.2011-3 WOF so far?

hi

 

thinking about to run BoS on a Intel Core i7 5820K 6x 3.30GHz So.2011-3 WOF

 

Anyone OC it and got some experience if BoS uses all 6 cores?

[Urra]

Don't have one. But Bos does not use all 6 as far as I can see. It only uses 1 all the time on mine. The gpu's seem to handle the rest.

hmm Bos use on my 3570k all 4 cores......

All four at 60-100% or just all for at about 25%? If the usage of all four cores adds up to 100%, than you are just using one core. Or better the game just generates enough work for one core and the CPU distributes the work for one core on all four.

so Bos scales, so i would like to know if a 6 core scales the same way like my 4 core does?

Since BoS seems to be quite CPU demanding and most SLI or CF systems seem to be bottleneckt by the CPU, atleast that is what it looks like for my SLI setup (currently only two 780) with a i7 4620K @ 4.6 Ghz, I would like to know if a six core CPU can do better than the four core ones too.

Sorry to bump this up again, but can anyone who has a 6 core (or higher) CPU share his experience and tell us unwashed 4 core simmers if BoS uses all 6 cores (12 threads) to their full potential?

I got 5820k and did a quick "look around" test on the airfield.

GPU (290X) and CPU(on 3.6Ghz) load was low though frame rate jumped between 40 and 60fps.

 

Optimization is bad. It seems I need to wait one more year before running the game again 

 

Before they took off advanced graphics options I was able to get stable 60 fps on my old system.

Forest view distance was the culpit for me:

I've been running an i7 5820K, MSI X99S SLI PLUS, GTX 780 combo for 3 months. All software is on SSDs. On a 27inch Hazro monitor at 2560 X 1440 with settings at ULTRA and the CPU oveclocked to 3.8 and HT enabled, I get 60 to 100 FPS. FPS seems very dependent on the weather scenario rather than AI activity - clear skies = 80 -100, overcast = 60 - 80.

 

I haven't done any benchmarking or careful analysis but, as per Task Manager, the cores seem to be at 50% most of the time. Per CPUID HWMonitor, GPU activity is at 99%. GPU temperatures are around 66C. CPU cores are  low 50sC.

S!

 

Got myself an i7 4960X (hexacore) and my first impression is that I got no increase of performance compared to my i7 4820K (quadcore). It even feels as if the FPS decreased a bit, I  am under the impression that my i7 4820K managed to give me about 55-63 FPS on the ground (LD Heavy metal, Bf109 F-4, Petrovska Airfield) where as my i7 4960X only gives me around 50-60 FPS.

 

This may be due to imagination. I also have to add, that the i7 4960X is only running on 4.3 GHz at the moment compared to my i7 4820K which was running on 4.6 GHz. Reaching higher overclock with the i7 4960X will need a bit more time. All in all I do not feel the two additional cores.

 

It is a bit sad that a 900€ CPU (got it for 700€ luckily) and 3x GTX780 (they are not the bottleneck) still do not allow me to get constant 60 FPS on the ground. I hope that the developers will CPU optimize this game a bit more, currently this game is very CPU heavy. Customable  graphicsettings would be nice too, to turn of CPU heavy stuff and get a bit more out of my GPUs.

I can't find the post anymore, but last winter devs said that BoS uses 2 cores, so you would benefit going from 2 to 4 cores, but having 6 or 8 would not give additional benefit.

[Zettman]

S!

 

Would be nice if one of the developers could clear this up or link us to a quote where it is stated how many cores IL2 BoS is using or better how many threads it is using. Since games or better their engines are not programmed to use cores but to use threads. So the real question is what engine is IL2 BoS using and how many threads does it use.

 

I don't expect it is using more than 4 cores. I found a sources that states, that game engines like Unreal, CryEngine or Frostbite only use 1-2 threads for rendering. There are also games that put the physics thread extra from the rendering thread (+1 additional thread) as well as Networking or Disk IO operation threads (+2 additional small threads). These threads are distributed on the cores of your CPU.

Would be really nice if we could get a clear answer on this.

Best cpu for BOS is still overclocked i5 let say 4,5 ghz... i7 is not a must in my opinion ,if you have that you just need strong GPU,but still i am suprised how well BOS run on ultra settings on my PC(see specs below)in 1080p ultra set. 2AA i got 45+ when am fly over burning Stalingrad and usually 60+ in air even with other aircrafts.

If you have a i7 you are not looking for a stronger GPU, you continue looking for a stronger CPU (higher clocks). I'm still getting 40-60 FPS on the ground with my i7 4960X on 4.4 GHz. My GPUs are only running on 40-60% usage. Will switch back to my 4820K soon, cause I can only get 4.4 GHz with my 4960X on voltages that are far to high for my taste.

Yes but your setup is pretty special 3 way sli and 3440x1440 res is just amazing no wonder that even OC i7 cant keep up.If you use only 1 GPU things looks much different i think.

Might be true, but I still can't get constant 60 FPS on the ground. That is a bit frustrating, I mean even a stock i5 should be able (when there is far enough GPU power) to deliver constant 60 FPS all the time, yet this game is so demanding, that even overclocked i7 can't reach that.

 

But to come back to the original question of this topic. It seems to me that a 6 core CPU doesn't hold any advantages over a 4 core CPU in this game. In fact most 6 cores are not as easy  to overclock (more cores that can make trouble  ) or run on lower stock clocks (if oyu don't want to overclock) as 4 core CPUs, so you may be able to see better results with a 4 core CPU that runs on a higher clock.

 

If I would build a new system today for this game, I would go with a i7 4790K that gives you a stock turbo of 4.4 GHz. It still supports enough PCIe lanes to run 2 GPUs in SLI/Crossfire which is more than enough for this game even on higher resolutions. So no need to go for the more expensive 2011/2011-3 socket CPUs that may over more PCIe lanes but slightly less CPU power which this game needs so much.
