My wishlist as an DCS starter: reduce shimmer & jaggies in VR.

[Vintageflyer01]

Yes I have doing the search for the solution and even tried a mod, but the shimmers and jaggies are still very disturbing when using a midrange/older gen VR set, like from Samsung, Occules or Vive. 

I’m afraid this effect will eventually keep away new players when they are trying the Free2Play, as I can speak from my own experience an half year ago. I know every VR game does have this aspect but in DCS, these are very big. 

 

My statement: Make DCS free of jaggies and shimmers.

 

Not being a computer expert during my search here and readings at the Nvidia website,  I know there are a couple of techniques that can reduce lots of jaggies and shimmer, without exchanging for a big performance loss.

There are indeed techniques to reduce jaggies and shimmering. They are artifacts caused by rasterization (fixed-size square pixels representing a continuum of sizes and forms - note that this can be more pronounced the fewer pixels  -- i.e. older -- your VR headset is, although it may be somewhat offset my the power of the GPU used) of near-straight (esp. horizontal/vertical) lines. A common method to counter this is called anti-aliasing (AA) often in conjunction with some form of a similarly aimed technology called super-sampling (SS) - a process that is applied after the initial image is rendered.

Shimmering is a related issue, and again some form of anti-aliasing (usually "temporal AA" where the previous image is used for this purpose) post-processing can help with this. The main issue here is that AA and SS (no matter which form), being a post-process, require additional performance - lots of it (this is in direct contradiction to the premise that "there are a couple of techniques that can reduce lots of jaggies and shimmer, without exchanging for a big performance loss". I believe that statement is mostly an incentive for customers to purchase a good GPU - as if there was any incentive needed  - we are using VR after all).

 

If your system is starved for performance (and with VR, no matter how powerful your card, it is), there currently is no way around some shimmer or jaggies when you want an acceptable image quality outside of jaggies and shimmer. The cards simply aren't powerful enough to provide adequate AA/SS at 90fps. Nvidia and AMD both advertise techniques to reduce shimmer and jaggies for their newer cards. They may bring some alleviation for those who own their respective newer cards, but if people are anything like me, newer cards also means these people use newer VR HMD, and those have even heftier resolutions (4896x2448 in my case). Yes, shimmer is annoying, and can even induce headache. I don't think that there will be an easy solution (Vulcan, DLSS, whatnot notwithstanding), so expect to have some form of shimmer for some time. If people are turned off DCS by that, that's unfortunate. That being said, shimmering and jaggies and all I still prefer to fly VR to any form of better-looking flat. It simply is so much better. Headache be damned. Let's hope Vulcan (a technology that allegedly is being integrated into DCS right now) brings some indeed much needed relief.

Yes shimmering is totally extrem in VR, did try so many settings and tweaks, none does really affect to get rid of shimmering.

Shimmering sucks and is hardcore annoying. Carriers, ships, buildings, planes, everything is kind of shimmering, even with all Anti Aliasing settings (MSAA, SSAA, MFAA by Nvidia - Settings)

VR Shader Mod also doens't help to stop shimmering,

Reshade Mod also doesn't help, its related to the game and its techniques.

 

Shimmering can really be frustrating and sucks, and every "VR" Video on Youtube, does not represent the real looking VR View a virtual pilot really has, it's represents the captured mirror on a 2d monitor or the track file with ultra settings for DCS uploaded for Youtube called something with VR.

 

Its like false advertising.

Hopefully ED does seriously work on VR or is paralel trying to rework the whole simulation for DCS next gen.

implementing TAA like in MFS should fix the shimmering. Although, it gets a bit blurrier.

 

DLSS would be the best option, but it's unlikely that ir would be implemented
