This is atmospheric scattering—an effect you see in the real world too! If you hop in an airliner (or, heck, even just climb a high hill), you’ll see that colors get washed out toward the horizon; things you see 100 meters away look much sharper and vibrant than things 1 km away, and likewise the limits of your visibility will be even less vibrant.

Just compare these 2 screenshots on Steam:

even when configured for a sunny cavok-day in summer xpl11 looks like that shot above, as if a thin layer of white was draped over it.

X-plane restarts and/or pic restarts don’t fix it in VR5. I’ll wait for VR6 to hit steam and let you know after that.

Right – except we don’t need an entire GTX 1080 Ti per eye, and if we did, we could look at making our code less demanding on the GPU – that would be the dev time we spend.

The headsets will grow more pixels and the GPUs will grow more powerful. Right now the GPUs are keeping up.

I think you misunderstand my question, with regards to the Titan V, that particular GPU is only available as a single card solution. SLI is not supported on a hardware level with that card. so, There is no possibility of using 2 of them. But I was referring to cheaper solutions such as dual GTX 10x series cards such as the 1070/1080/TI which I now own 2 of in my current rig. and is much more common GPU solution among PC enthusiasts and flight simulator users. The price of dual card solutions is significantly cheaper than a single Titan V. but that only becomes a viable purchase performance wise, If OpenGL SLI for VR is implemented. Otherwise, your original premise of purchasing the largest single card holds true. For most average users. This will be a 10x sseries in multi card configuration. And only this configuration of dual cards running OpenGL SLI for VR can reach and even greatly exceed the VR performance level of a single Titan V. which is the reason why I asked the question.

Thanks for the feedback! Looking forward to VR6.

I just set it to 45fps and its better on my rig (1080Ti)

Dual GPU VR isn’t a priority for us right now – basically it requires coding dev time like all other performance improvements, but it has a pretty bad “payout” for our users on average because it requires _two_ GPUs. Given that two small GPUs is only useful compared to one big one for VR and other specialized apps, users are better off spending their budget on a single bigger GPU, which means that the only users who will have dual GPUs are ones whose GPU budget exceeds the price of a single high-end enthusiast GPU. The Titan V is currently $3000 so supporting acceleration via 2 of them is going to hit only users who want to spend $6000 on GPUs.

Our resources are better spent finding other ways to make VR faster, e.g. optimizing the rendering pipeline to require less GPU power.
