VR Optimization Guide - DCS 2.5.6.60

I hope that whichever voice actor that ED hires for the ATC overhaul, it is the same dude from Falcon 4. That southern accent was classic, although it was so long ago, he probably looks like Mick Jagger by now.

ED forum discussion of DX11 mode use in SteamVR. TLDR: helps people whom are GPU bound, but may decrease image quality.

I still love the guy from the original A-10C tutorials. I get the feeling he suffers no fools.

I need to get better at explaining stuff. :slight_smile:

Explanation seems good in that quote. You just need to put a clickbaity title or header over it to get the message across I think.

Sometimes Troll understands. Sometime he doesn’t.
That’s not your fault… :wink:

Preeeeeetyy sure it is just Quality Out → Garbage In for my communication interface. I’m just a slow learner. Or my SSD is full. A bit of both.

I think in this case I sort of ‘hid the lede’, in that I packed lots of noise around the answer in why the 0.5 actually helps, because it is doing less stuff. Sometimes videos are better as well. Both jabbers and wooz do a good job explaining things.

Not for me. I prefer reading instructions and explanations. I need to adjust the speed at which I consume the information. I think I have a bandwidth limitation… :slight_smile:

I guess it isn’t always pure math too right? I mean…does the workflow (or programming I guess?) of how you get to the end result much matter in these things? I mean…if SteamVR is doing something more efficiently than DCS World (or vice versa)…we should bias our systems toward that which works the best most efficiently right? Or are they both doing exactly the same thing in exactly the same way?

At least it isn’t as frustrating as X-Plane. I could exit X-Plane, come back in with NO changed settings and find wild variations in experience from one session to another. I don’t know if that means it was keeping stuff in memory or a cache or something…but there are a lot of ways weird things can happen when trying to compare apples to apples. It does seem Jabbers had some nice tools to extract the data with. He talked a lot. One could say…he…Jabbered…

No, there are doing different things, but people have different bottlenecks on their systems so it’s hard to offer global advice. DCS is CPU bottleneck’d generally, so if you use PD 0.5 and then ask it for a 10% smaller screen to draw because of that then it’ll improve FPS - the other side of the coin is that the GPU is doing lots of work oversampling (like to 500% etc) that image buffer DCS gives it, and then makes it look nice. If you have a poor GPU (or DCS isn’t doing much etc) then this could be bad advice, so it nearly always depends.

You’re right in saying that it doesn’t matter how you get there though. For VR especially it is all in the eye of the beholder, as we all have different eyes and tolerances for different quirks. There are almost infinite knobs to twiddle in the game->eye stack.

Which knob has the biggest effect on ‘shimmer’? I have 2x MSAA on but still get a lot of shimmer on power lines, rivers, hangars, things like that. I’m willing to give up some FPS and visual clarity to get rid of shimmer.

Gosh, this gets outta hand quick. I’ve re-arranged things, again, and have it as good as I can get, with my system.

Making an oath to myself: “I shall not touch these things again, ever”. On this machine :slight_smile:

It’s tough as the best answer is more anti aliasing (MSAA in DCS) but it’s hard on performance at VR resolutions. Some things to try:

  • Reduce PD in DCS in steps and up MSAA to x4.

  • Make sure AF is at least x8.

  • Turn off MSAA but up the SteamVR SS resolution very high (it’ll acts as a form of AA, but can be hard on frames).

  • Turn off Motion Smoothing to see if it is exaggerating shimmers or not.

Was planning on just spending some time online trying different VR settings. Then I found myself on a training server in a Hornet (LWin Home to the rescue!)…and as always is the case…found myself completely enamored with doing cats and traps endlessly. Started with 5K fuel…did a bunch of landings…took off with 800 lbs., found the S-3 with 300 pounds…and hit the basket on the first go! Woot! Of course…I only stayed connected to about 800 lbs…hit it again (and again) to 2,000 and went back for more traps.

Sound boring huh? :rofl:

Yep, that’s exactly what I do. :slight_smile:

I tend not to MP as I’ve got the integrity check unfriendly VR mod. There is another version of it but not sure what the cost is on FPS. Anyone know off hand?

That is the one I downloaded. I haven’t tried the non-IC version. I was pretty happy at 56 Steam SS and 1.6 PD in game. I’ll bet I can go higher with Steam SS though. I’m horrible at using valid testing techniques though.

I’d hit ya up for some MP but the boys had soccer rained out today so we have make ups at 8AM… :yawning_face:
