are we sure 4K is the same as VR?

in a perfect world, all usb devices would use unique identifiers, so the operating system could identify them, regardless of which port you use. but a lot of usb peripherals, manufactures reuse the same VID/PID identifiers and skip the device serial number.since it’s easier and cheaper that way, and we base our purchase decisions on price. thus... Houston! we have a problem.

for real? this is contrary to almost every review out there.

across the overall DCS user-base? or just those of us who read these forums every few hours? ; ) i think those of us reading this thread are a very, very, very small portion of the overall DCS user-base and very unlike the "general" user that pays most of the bills and keeps DCS in business.

There is a huge impact, because each time a thread awakens on a diferent core, he has lost his L1 and L2 cache data, and it has to load it again from DRAM ... theoretically yes, but in generalized workloads (games, sims, netflix, even DCS), anything that is not 100% compute, it makes no difference. you see this all the time when users post their perf data after spending hours and hours "tweaking", pinning dcs to a subset of cores, or trying get the process lasso magic to take. we don't have low level control of the scheduling so all of this is wasted effort.

to be clear, a thread is a a list of instructions that get processed. each application has at least one thread, but most have many threads (DCS often uses 50+ threads). A core is the physical hardware that works on the thread. It's the part that actually does the work. The operating system will schedule a task (a thread) to a core to execute when it's ready. If more than one thread is ready to run, then both will each be assigned to a free core and they will run simultaneously (at the same time). When you limit DCS to one core, you are asking the operating system to take all 50+ threads and run them one at a time, on that single core. It's no wonder you have sound stutter problems. If you limit DCS to two cores, you are asking the operating system to take all 50+ threads and run them two at a time (one thread on each core). Obviously, this is much better. But better still, is to allow DCS to schedule those 50+ threads onto any available cpu cores. maybe 2, maybe 3, maybe 8... it depends how many threads are ready to run, and how many free cpu cores you have. The only time DCS uses "2 cores" is on the old Core-Duo chips from 2008... and that only happens to be true because there were only 2 cores in the whole cpu ;)

this is not a valid test. if you limit the number of cores available, the operating system will just reschedule the work to the available resources. it’s exactly what an operating systems job is, to manage resources! you test does not prove that dcs does not use more than one core. what your test proves, is that your one cpu core is not fast enough to do all the things dcs needs to do before the sound buffer runs dry. thats completely different.

Do you mostly play Single player or Multiplayer? This is very much not true. but it’s a great slogan and marketing soundbite!

you can’t really use 4K benchmarks to judge VR performance. the api’s are different, the render pipelines are different, the number of times the cpu has to calculate and generate the geometries is different. if you want to compare cpu performance in VR, you can really only do the comparison in VR.

maybe at one point this was the case, but i don’t think this is true anymore there have been multiple posts here that show DCS uses a bunch of execution threads and each of those threads can be assigned to separate cpu cores (unless limited by process lasso, or some other utility).

CPU for DCS VR: new AMD or 9900K you know some of us purchased a 2080TI, right?

what’s the cost of the MB fan?

with all these problems, it’s no wonder consoles are so popular. unpack, plug-n-play and you’re gaming in beautiful 4K, in minutes.

this is correct. pagefile is just “temporary” storage. let windows manage it. most of the “pagefile” posts/youtube tweaks are referencing behavior from 2008 or earlier. they are no longer needed.

Latest Benchmarks - Intel vs AMD what do you mean by utilize? any app can use more than one core if it’s coded to do so. i would reduce expectations of “vulkan”. it’s not a silver bullet. there is no magic. it’s just a more basic api that lets you get closer to the metal. it’s nothing different than what we could do in the old days.

true that. these 3000’s were hyped pretty heavily here in the forums. both by the ‘experts’ and by those who interpret spec sheets. seems they were wrong. it would be interesting to look back and see if was the same group who said the rift-s would suck, before it came out.

‘purchase’ isn’t that useful in any case. we all plan on purchasing things (corvettes, jewelry for the wife) and most never follow through. so having a poll for “wants” provides dubious value

70% VRAM Usage on Menu and 100% on missions with 2080Ti keep in mind that a lot of stuff in vram never gets used for anything. it’s often used as a simple holding area, “just in case”. that’s one of the reasons vram usage goes up, even before the software knows what random choice you are going to make.

you hit the nail on the head! it’s why we subscribe. otherwise no one would listen to us.

70% VRAM Usage on Menu and 100% on missions with 2080Ti i wouldn’t think so, vram doesn’t typically make a huge difference, but if you try it please post your results. i would be very interested to hear about your experience.

i think you’d be surprised by how much you can do with a dedicated server.

ok that was funny :) but to put it in perspective, the extra $2/week i spent was well worth it. and cutting out that extra sausage roll each Sunday morning before church has helped my health too.

you guys sold it i now have a huey in the hanger!

is the CPU’s are comparable, and the operating system is the same, then it comes down to device drivers?
