What is SSLR?

I believe its called Screen Space Local Reflections. And yes, same here. I fly at 4k and FPS went from 59 (I capped my game there not to hit G sync upper limit) to 24 - 40.

Looks pretty nice if it works. I wonder if the Nvida ray tracing could help with this.

I am afraid they are two different technologies. Screen Space Reflections are the reflections projected from what is displayed only on your screen, whereas ray tracing also shows reflections from the offscreen. Probably DCS is not making any use of RTX right now.

Darn...

 

IDK, I wish they would figure out how to use RTX to do "something" (like realistic radar).... But I know I know they don't want to favor one false choice over the other.

Not sure about night time, but it doesn't seem to make much difference in appearance in the F/A-18/Free Flight/Persian Gulf mission but it does eat up about 20% of the FPS overall. In the F/14/Cold Start/Caucasus, the reflections off of the bomber taking off seem to be brighter, but it could just be my old eyes wishing they were, too.

Tying radar functionality to a Nvidia proprietary gpu would be a really stupid thing to do, even if such were possible.

I stand corrected

Ray Tracing is not owned by nVidia. RTX is a nomenclature used in the 2000 series versions.

It isn't. It's part of the lighting update, but the patch notes don't go into exhaustive detail on the specifics.

Ray tracing can be done on a CPU, (where its presumably done now if we actually bother to model it) it would be good to offload that onto the RTX protion of GPU that's literally doing "nothing". Yes I know AMD doesn't have it (yet). But presumably they will in due course.

 

The whole AMD vs NVIDA thing is mostly a scam anyway, illusion of choice and all that. It would be more work for ED, but probably worth it in the long run given how "performance" is.

+1. Next gen consoles will apparently also support ray tracing, so it seems like the hardware is here to stay. And it'd be a shame to have it sit idle.

I believe this new setting is only for the water at this stage - i tried it and in VR lost 30% of fps - was quickly disabled again.

Yep, with this option on, I get fps drop below my frame limited 58 in 4K for the first time. It has sent my GPU fans into orbit!

 

It isn't obvious to me what the benefit is anyway. Where is best to look for the effect SSLR has?

I believe that LLSR is always activated even in the OFF option. This would justify the drop in performance.

I think you are right. I also think it is always on. In some missions there is absolutely n9 difference between off and on.

Of course you can use a rtx cpu system to simulate a radar, but what about the impact on performance? We don't need a 1:1 scale reproduction but simply a sufficient approximation.
