Very strange GPU and CPU usage.

[ElCuco68]

I downloaded MSI Afterburner, so I could monitor processor usage in game while in VR. I'm currently using an AMD FX-8350 until I can get an 8700k or 7820X (which is better for VR, by the way?), which I overclocked to 4.6 GHz at 1.5V. I have a watercooled EVGA GTX-1080Ti, 32Gb of DDR3 1866MHz RAM, and various SSDs and HDDs. While flying, both CPU (all cores roughly the same percentage) and GPU stayed between 30-40% (!). Not at all what I was expecting. DCS never went above 28 fps while flying; looking at the ground at low altitude brought it down to about 20-22 fps, which was making me nauseous. CPU went up to about 65 degrees C, at 4.61 GHz, and the GPU stayed below 55 degrees C. I'm using that mod that raises framerate, btw.

What's going on, and how do I fix this? Or, does this mean that that 8350 is strangling that card?

[Mars Exulte]

1.5v is really high for 4.6. I had the same processor and did not need nearly that much voltage. Also yes, the CPU is strangling your GPU. My fatger recently reported substantial gains on a 1060 6gb going to a Ryzen 2600x over his ridiculously overclocked FX8300 (he won the silicon lottery and has a stable overclock @ around 4.7, I believe a full gigahertz worth of ocing).

 

So with that in mind, a 1080ti would most definitely be choking.

 

-edit

DCS does not currently utilise large numbers of cores, so the low usage is probably an average from the process getting floated around cores.

The latest build has added a shutter problem for the rift in 2.5.3.21016 Open Beta. There is a hot fix, not sure if fix? I'm updating now...

 

What graphic settings are you using ElCuco68? I hit the VR preset button then up the textures and view to high and have PD at 1.6

 

These are high settings for just very small missions and laps around the boat in the F/A-18 etc. If I play larger missions, I will have to lower the settings down a little to hold 45 or wring the neck out of my GPU and CPU to hold it.;)

[ElCuco68]

I'll get a screenshot of the settings. By the way, I have an opportunity to get a 7820x i7 for the same price as an 8700k. Should I get that instead? It expires in an hour...

well well....they both perform equally in games but the 7820x is more designed for workstations and stuff like that like video editing..etc

 

oh and btw you're living in a nice place mate

Thank you! Yes, parts of Enfield are pretty. Of course, we have our ghettos, and this is Connecticut's prison town (we have about 8 or so prisons here, including the "supermax" and Osborn, where we have our "death row".This town used to be the property of the Shakers, which I believe was a religious sect that was relatively prominent here around 1900 or so. Then for some reason they sold the property to the state, and the state took this pristine land and turned it into a prison complex.

 

My family is originally from Naples, Italy. Do you live anywhere near there? I visited there once when I was a crewman on a submarine, back in the 80s. I'd like to see more of Italy.

 

How does that 8700k work with Oculus? I'm going to replace my 8350 with an 8700k, but I'm hoping I don't have to get new RAM right away (I have 32 GB of DDR3 1866 MHz.

[Mars Exulte]

Something like an 8700k is only going to be on a new motherboard, which will mean DDR4. You're at the point of a full overhaul unfortunately :) I'm going through this whole thing with my Dad, too, for much the same reasons.

[ElCuco68]

So you can't use DDR3 in a new MB? Damn!

[ElCuco68]

In your opinion, am I just putting off the inevitable by waiting to change to the 8700k? I mean, if I'm not seeing what this card can do in the Oculus because of that old CPU, then I'm just going to have to bite the bullet and do this overhaul. With the DDR4, if I indeed need that, What point frequency-wise is the point of diminishing returns? 2400 MHz or so? In other words, I don't want to shell out hundreds of dollars more for super-fast memory if the only yield is on paper.

[ElCuco68]

okay, here's the settings and the CPU and GPU utilization. FPS never exceeded 30 fps during this.

[Mars Exulte]

Honestly RAM speed is not that big of a deal. WhenI bought mine, I got 2666 because after that point the price increased drastically. When I bought stuff for my dad I got 3200 for the same reason. It just depends on what brand you want and how fancy you get. I personally don't exceed an avg of about $10 a gig. For example $160 for 16gb or $300-320 for 32gb. Get whatever is fastest in that range and you think looks cool. I got Corsair DomPlat back in the day, but my dad's I got Gskill Trident with the aluminum heatsinks. It's more about aesthetics than performance, really.

[hansangb]

There was a video that showed the side by side difference when faster DDR4 (2666 or 3200MHz, I think?) vs DDR3. And I do recall seeing a bigger than expected difference. If you google around, you may be able to find it.

 

 

And yeah, you're going to have to bite the bullet sooner or later.

[Mars Exulte]

Oh, from DDR3 to DDR4 is a big jump of course. But the difference between 2666 and 3200 etc is not so great :p That's what I meant

I believe I saw one report where above 2666 it was diminishing returns.

[ElCuco68]

Well, I just bought a binned (5.2 GHz at 1.41V) and delidded 8700K with copper heat spreader, and an Asus ROG Maximus X Hero MB, an EVGA 1000W PSU, and 2 X 16Gb Corsair Vengeance DDR4 3000MHz memory sticks. Is there still a way to download Windows 10?

[BitMaster]

If you own a retail copy of 7 you may still be able to enter your 7's license number when prompted.

 

 

and yes, you can dl the win10 iso image from MS directly, it's a tool that will either make you a USB stick or save the ISO image. Google it: Win10 ISO Download , take the MS link

Hey, it looks like you've got more or less the same system I'm getting! How well does everything work with Oculus/DCS? Can you give me some pointers on the best ways to squeeze performance out of this rig? By the way, here's my current settings, and what I'm getting for specs:

[ElCuco68]

Turns out the pictures of the settings are in page 2 of this thread, and I can't reattach them.

[ElCuco68]

Also, do you think the Corsair H100i watercooler will be enough to OC that 5.2Ghz CPU I just bought? It was delidded, lapped, binned at 5.2GHz/4.2V. What about the EVGA 1000W PSU I just got? It's this one: https://www.amazon.com/dp/B00EKJQM5E/?coliid=I1YX8O8G8ER3DP&colid=96CTP6TLMOOS&psc=0&ref_=lv_ov_lig_dp_it

 

I'm thinking about adding this to put the OS on, or maybe even getting a 1TB one to put the OS, Oculus, and DCS on. I've already got the OS on its own SSD, and Oculus & DCS on a bigger SSD (both SATA), so do you think, considering the CPU and GPU I'm going to be using, that getting these would improve performance and/or loading times? What about your other HD arrangements (RAID-0 and so forth)? How might that help? I don't want to piss money away, but I figure that if I'm going this far, I'd might as well do it right, if it would really help.

[BitMaster]

The H100i is one of the best performing AIO out there, so yeah, that should work well.

 

 

The PSU looks good too, Titanium and 12y warranty sounds like made by Seasonic to me.

 

 

 

Your CPU is at what Voltage ? 1.2 is rather likely than 4.2, that is sure death !

The Voltage you set is one thing, the voltage the board actually applies is a totally different game, unless you disable SVID and choose manual voltage settings for the CPU. Mine then needs 1.35v in idle, under load that drops only little to 1.33 or so, LLC6. 5G I run at 1.30, manual, SVID off and LLC6.

 

 

I only run the Raid-0 to combine the space of those 2 256GB drives, 1 x512GB is easier to use than 2 dribes 256GB. I rather had another 512GB or 1TB NVMe so to say. I just happen to have more SSDs than I own NVMe.

 

 

What makes sense is to have 1 drive for the OS and 1 drive for all your BIG apps like Games, Adobe, CAD, whatever. NVMe is the fastest atm, 2 Sata SSDs are ok too but prices are so similar I'd go NVMe 1x 512GB and 1x 1-2TB, than add Sata SSD and HDD as you need them. Mind the Sata 5+6 trap with a 2nd NVMe in use, RT(F)M ;)

 

 

I havent used Rift in the last few month much, honestly, I am the wrong person for the current DCS patch level to ask. I enjoy it if I have the time

but hardly ever get to my DCS before 10pm and already half asleep, that seems to cause nausea for me. Once my life relaxes and I have more time I might be able to use VR again. For now..I may give it to my son or sell it if I cant overcome my dizzyness after 15min.

 

 

For your OC qualify runs, you may wanna install CoreTemp to watch each cores temp, also HWinfo64 alomg with MSI Afterburner and CPUID, those tools are like the minimum standard toolsets most overclockers and gamers use, there are more if you want more ;)

 

 

When mine is under full load prime95 with AVX small FFT's 12 Threads my temps get to high 80°C, like 87-89°C. In DCS I may reach 55-60°C now in summer, on cooler days it's in the low 50s.

 

 

Try to get your Volts as low as possible, I really recommend SVID OFF and Manual Voltage if you run an Asus board, others may differ.

[ElCuco68]

Yeah, i screwed up; meant to say 1.4 volts. What is SVID ? LLC6? What's the SATA 5+6 trap? Sorry, I'm a Luddite.

[ElCuco68]

If I had to choose either putting the OS on an NVMe or my games on a bigger NVMe, which would you choose? In other words, which would benefit more from that speed?

[BitMaster]

I`d put the OS on NVMe and GAMES on SSD if you only have 1 NVMe.

 

 

SVID is the CPU talking to the board ( and giving CPU wattage info to HWinfo or most other apps for example ). When SVID is ON, your Volts may be significantly higher than dialed in. For OC put it to OFF.

 

 

LLC is LoadLineCalibration:

After putting SVID to OFF and setting Volts to 1.35V for 5.2G ( or 1.4 in your case )( they call that binned at 1.4v ?? ) you volts will be 1.3500 during IDLE !! When you load the CPU the volts will DROP and may crash your system, in order to buffer that, LLC is used. Be warned, all vendors use LLC with different modes, sovAsus LLC6 might be LLC2 on a Asrock board, do not take the numbers across vendors. Asus applies more juice with higher numbers, LLC6 is second highest. My CPU only drops very little when fully loaded. Any lower LLC crashes prime95 small FFTs or other serious tasks after some time. LLC6 is bet yet I have found with lowest overall Volts.

[Mars Exulte]

There's really no practical benefit to using an NVMe drive at this point. You'd be better served by buying two or three cheaper sata SSDs and linking them in a raid. You'd get 1-1.5GBs read/write for half the price (yes, a NVMe does 3.5R/1.5W. ... it also costs a small fortune and that is massive overkill)

[ElCuco68]

exactly what type of RAID setup? By the way, what do you think of this? It doesn't have those high (3.5Gb/sec) read/write speeds, but it seems plenty fast, and seems cheap for an NVMe stick:
