Quick Checks for Improving VR (DK2) Performance in Horizons Beta

Of course this is subject to change, but I thought I would share the tweaks in game that I made to fix stutter.

It boils down to two major settings, at least for me. I am running 2x GTX 980 in SLI. Using the same settings that have worked great in 1.4 and 1.5 beta, I found myself with major stuttering in Horizons.

Some people suggested things like terrain quality...etc, but my stuttering was occurring everywhere, not just on planets. With my changes, I still have both terrain qualities on ultra without trouble, and they appear to have very little impact on my performance.

I found the two major settings are:

Super-sampling and HMD image quality. In the past, HMD image quality was basically worthless, it didn't seem to actually do anything for me. I slid it to max just because. Come Horizons, and suddenly 2x super sampling and full HMD image quality looks pretty good... as long as you hold perfectly still.

Thus, From running full 2x super sampling, and full HMD image quality (all of the way right on the slider), I have moved to being 2x super sampled and 3 clicks of the HMD Image quality to the right.

Both of these settings appear to improve the image quality fairly evenly with similar performance hits. I would personally suggest you toy with these two major settings, balancing them as best as possible. I would personally suggest you set HMD quality down to the minimum setting to start, then super sample to the highest possible choice you can do without stutter.

Once you have found the highest super sample (2x may be still no problem for you), then begin sliding the HMD image quality one click at a time until you get stutter, then set it back one. I find one of the best places to test this is on the "surface" of the stations in space.

Hopefully this helps you guys avoid headaches.

I am not absolutely positive, but I am actually pretty confident the ending graphics quality is on par with the previous versions, once you adjust these settings. Much of me thinks the HMD image quality was just broken in the past or something. Suddenly, it has taken affect, and it may be what is causing most of people's problems.

Best wishes with VR and your planetary landings! Have you found other settings to be dramatically important? Feel free to share what you have found.

I had serious judder - then read about NVidia Inspector needing to be pointed to the 64k exe........did that and.....

BOOM!

All stutter gone and enjoying the experience.

6.01 SDK, 970s in SLI and Win 7

Would you kindly tell in detail what you did? I want Frames too!

I have it on custom - some mostly HIGH.

Shadows LOW
Blur OFF

Turned some terrain stuff up but judder returned in the SRV - went nack to medium on that

Seeing as that is no help, borderline incomprehensible even. i will share something that helped me out

Basically up until horizons i was using Nvidia DSR to run at 2.25x 1080p resolution. this was great in a lot of ways but had a big impact on performance and still left a lot of aliasing/jaggies/flickering

What i have found lately though a lot of tinkering is that FXAA is suprisingly effective in the DK2. Enough to stop me using DSR at all. Now because FXAA is a post process AA that uses a blur filter it does make certain things in the distance a little blurry but its much much better than the constant flickering of edges i was getting at 1080p before. it sort of 'stabilizes' the image in the rift. I think that's the best way to describe it. And performance is much better than super sampling

Yep turning Shadows to LOW, it's will make the biggest difference to your performance without sacrificing much quality. It's where you should really start first, since it seems to default to Ultra.

Glad you understood it - and that it helped :)
