Improvements can be made without VRworks but they certainly won't be as big as adding VRworks. We are basically having to buy higher end GPUs because they aren't being fully utilized in VR. When u combine an ageing inefficient DX API with lack of VR hardware performance features of 1000+ series GPU then you lose a ton of performance. It's like trying to heat a room in winter with the front door open. The ultimate performance boost would be VRworks + Vulkan.

I'm referring to VRworks... It was added to Eve Valkyrie, Raw Data, Croteam VR games and a few others. Prior to VRworks support on Eve and Raw Data, I could only run the game in VR on medium settings. After VRworks I was able to max-out these games. Raw Data suffered performance drops for me even on medium settings at times. Since they added VRworks I am able to run the game smoothly on the highest settings. DCS World needs all the performance boosting it can get for running VR. We have GPUs that aren't being fully utilized for VR users. I have 2 x GPUs for 3d rendering.. If VRworks was supported I'd be able gain a big performance boost.

Utility does not work. Can't even choose DCS version number from drop down box. It's empty.

OK, then I hope to buy it down the line. :)

I'm confused... By the VR comments in this thread. Main page says VR not supported but some of the comments in this thread seem to be discussing issues with CA in VR???? I'd buy CA if VR support was there but there's no way I buy tiny 2d rectangle games/sims these days.

Not a kickstarter this time fortunately... https://www.vrfocus.com/2018/07/plexus-unveil-affordable-option-for-vr-haptics/ Affordable VR haptic gloves. I have no connection with plexus but many VR users want to see finger sensing support for DCS World.

On the negative side... one of those new users was ranting on facebook last week because DCS aircraft were very hard to fly with "keyboard and mouse, can you please make the game easier to fly?" That particular new user was quickly educated about the existence of flight controllers and subsequently purchased a "joystick".

It wouldn't be so bad if we weren't running ancient code. Single core flight sims? Really? I have 8 cores and 16 threads! Or how about that grossly inefficient DX11 API? Vulkan or DX12 could release a whole lot of graphics power locked away in these GPUs. And how about VRWorks for Nvidia users? Eve Valkyrie and Raw Data used to stutter at higher graphic settings on my 1070... when the respective devs added VR works I could max out those games in VR... insane level of detail on a 1070 with no frame drops. So a 1070 is technically capable of running DCS World smoothly in VR if ancient code wasn't dragging down performance. Forced to buy a 1080ti to try and compensate for ancient code. Not good.

I find the Mig 21 and A/C with lots of analog dials drag down performance compared to the modern glass cockpits. I could really do with a 1080ti for 3d rendering anyway. Birthday coming early march so maybe a good excuse?

I will log the CPU usage in 2.5 this evening. GPU usage hit 91% but average 80%. 1070 Overclocked. I guess I'm gonna have to go insane and buy a 1080ti.

Thanks for input! So I just followed your test... VR disabled...DCS 2.5 at 1080 res. Viggen cold start training mission. In-game FPS counter shows about 120 when I'm starting up the aircraft. When I start taxiing for takeoff the FPS drops to between 90 and 84. In the air it varies between 129 and 90 with some dips down to 84. GPU is overclocked +140 +500mhz. Cinebench scores 1700+ CPU is 3815. It has gone to 9ghz but can't get it 100% stable there. I couldn't try your 4k test as my monitor is 1080! Since doing the test I have increased the auto fan speed profile on GPU. Don't know if any thermal throttling was taking place. I will redo the test logging GPU temp. It's a shame I can't get my system stable with 3600mhz ram since game FPS increases with infinity fabric speed. The timings at 3466 are 16 16 16 33 and were optimised via a ram timing calc. After setting the timings, windows booted faster and was visibly snappier and the cinebench score is consistent at 1700. Ram timings are "optimised-safe" so there might be extra headroom if I redo the timing calc with more extreme option.

Have u checked your CPU and GPU temp with DCS running?

A friend a mine has an octopus rift and I tried DCS 2.0 Nevada with it on my old i5 2500k PC. ASW gave it a good boost. Vive doesn't have that luxury. Reprojection Async is pish. Stops judder but does nothing else.

Just read this... https://www.pcgamesn.com/amd-ryzen-2-release-date-specs-performance Don't expect much boost from Ryzen 2 in April. Slightly higher clocks and 10% boost from 12nm. DCS runs very well without VR on my 1700 but I ain't ever gonna go without HMD.

It's a crazy situation. We have all this new hardware and it's being crippled by ancient code and API. DX11 bottleneck. OpenGL bottleneck. I have a GTX 1070...I run VR and there are very few games that make full use of the VR features of the GPU. Raw Data and Serious Sam support "VR-works" and I can max them out graphically with no fps drops. I came very close to ditching my Ryzen and running back to Intel today but Bitmaster is quite right.. an 8700K won't boost performance enough to power an ancient API.

Always one or two steps ahead. I kind of suspected this when running the Mig 21 on DCS 1.5. FPS was so low even when I tried it with a 4.5ghz coffee lake i3. Performance is better since 2.5 but I guess we really need Vulcan. +2 Bitmaster

Only ever owned Intel CPU's since the days of 386sx. Built my first AMD system last year... Ryzen 1700 @3.8ghz, 3466mhz ram. I'm having a hard emotional struggle living with 3.8ghz overclock. My old i5 2500k was clocked at 4.8ghz. I need ALL the FPS I can get because I run VR (HTC Vive doesn't have the benefit of ASW). I'm really close to buying an 8700k and ditching the Ryzen. I'd keep the DDR4 which is rated at 4ghz and overclocks to 4.4 or 4.5 on Intel (stuck at 3566 on Ryzen). Ryzen does well at screen res above 1080. Ryzen+ is coming eventually but rumour is that we'll be lucky to reach 4.3 or 4.4ghz with it. I do 3d rendering so that was why I chose the Ryzen... however... My 3d rendering is ALL done on GPU via octane now so... My GPU is a GTX 1070 overclocked +140 core and +500 Vram. For flight sims and games I only run VR. Never play in 2d now. Thoughts on VR + 8700k versus Ryzen?

Yar, primary use is 3d rendering but I do like my vr and i can't help wanting high gaming fps. I love overclocking as well so would be aiming for beyond 5ghz.

Mig 21 is pretty much unusable at this time in VR (vive). I'm running a Ryzen 1700 at 3.875ghz, GTX 1070 and the fps is too low for this aircraft particularly on dcs 1.5. 8700k brings a needed FPS boost but I'm wondering if it would make the mig 21 playable? My guess is that even at 5ghz plus it wont....

Lol. Sorry... M2000. Don't know why I was thinking Eurofighter. Mirage and Viggen both run perfectly smooth in VR.

It's a very CPU heavy simulation isn't it. I thought DCS would get a massive boost when I ditched the ancient i5 2500k but no... If I stuck to the glass cockpit aircraft I'd get a very consistent frame rate in VR. IL-2 on my i5k with GTX 1070 on Vive was borderline playable. Since piezen 1700 at 3.87ghz it's a bit smoother but not massively. I have to go easy on graphic settings. I'm gonna record CPU and GPU usage during play for DCS and IL2. I guess it's early days for these sims in terms of VR and also from experience - steam VR isn't as well optimised as Oculus runtime. I have no plans to return to Octopus at this stage though. I like my laser tracking.

I'm running on Ryzen 1700 at 3.875ghz 2927mhz 16gb DDR4. Old CPU was i5 2500k at 4.8ghz. DCS World is better but still not able to run Mig 21 with HTC Vive. Different aircraft require different amounts of CPU... Anything with lots of analog dials is a big drain on performance. EF2000 with its glass cockpit was ultra smooth in VR on my old i5k but mig 21 isn't viable. I'd like to know how it performs an intel 7700k at 5ghz on HTC Vive.

Yeah but not enough to pull the mig 21 up to 90fps in vr.
