tune with system tab mirror settings The rearview mirror frame rate is low.

[supersylph]

The frame rate of the three independently rendered rearview mirrors is too low，It is not so low on the F15E.Is there any possibility of further optimization?Or perhaps provide an option similar to the old rearview mirror rendering method?

[Xtorris]

New mirror options were added today. Try those.

今天添加了新的镜像选项。试试看吧。

Thank you very much. I tried lowering the settings, but it still wasn't ideal.I was able to get good frame rates on the rearview mirror on the F15E and F1. They are also individually adjustable.I hope ED can be optimized in the future.

Doesn’t matter what I set this to in options frame rate in mirror is very choppy or at least what I am seeing is very choppy however I have decent frame rates in game? This is the only module where this happens can it be looked into. I use VR. 

 

EDIT: I apologise ED I jumped the gun, for some reason after restarting the game, and setting mirrors at 512 every frame the picture in the mirror is much smoother and mimics the rest of the gameplay. What I was forgetting was I needed to restart the Sim to apply these changes, as in the past you often get a prompt to say restart to make changes, and I didn't look and see the small *. But at first when loaded the Mig 29 mirrors were terribly slow. I advise if anyone experiences this experiment with your settings but remember to restart the sim. 

 

Overall I would like to say it feels dynamic, its a lovely flight model, and overall its so much fun to fly. It feels like the most convincing flight model in DCS, I'm no jet fighter pilot but I have flown aircraft and this feels great in my view. I've waited a long time for a proper Mig 29, it feels like it really belongs in DCS and is one we should have had from the start. I love this thankyou.

I’m glad you solved this.  I had the same exact problem, but it was happening on the FC3 Mig29, the Hornet, and several other modules.   I made some changes to the mirror settings with no effect.  It was bothering me enough the first night of the release, that it actually gave me VR nausea.  
 

I decided to shut down my computer and VR headset completly, and when I fired everything up the next day, I no longer had slower frame rates for the mirrors.   I’m glad for it, as that was truly horrible in VR lol.  Hopefully it doesn’t return!

Oh? so far I haven't been able to get the new settings to work. It is indeed a horrible experience in VR. In fact, the new "sequential rendering" which is supposed to improve performance, reduced my framerate even further.
I'll try turning them on again later then.

[Cgjunk2]

If I recall, I currently have the mirrors set to the max resolution, and turned off sequential mirrors.

I’ll report back if I start experiencing low mirror FPS again.

DCS used to have the option of setting lower resolution on mirrors which worked well.  But then that option disappeared for a while.  This new system, when it drops the mirrors into low FPS, makes it seem like the mirrors are running on a seperate CPU processor.  It’s a very weird, disjointed effect.   That first night it didn’t always run in low FPS, but it seemed to drop into low FPS based on graphical demands.  It was weird because it happened even if the mirrors were set at the lowest resolution.

 

edit: I know this was marked that the solution was to tune the mirror settings, but I tried that the first night and nothing changed.  Even with changes to the sequential mirrors.   I didn’t think a restart was necessary for changes to sequential mirrors, but maybe it does need a restart, since my problems went away after I shut everything down and restarted the next day.

Yes I just tested the new options and the mirrors do indeed work properly now. As in, fluid movement and fairly high resolution but they still cost me 20% of my framerate and the sequential option does nothing (on my system) to improve their performance.

Generally speaking, Is the frame rate penalty with mirrors on the same as before?

On my end the mirrors look great now and performance is good too.

I use 1024 every frame option (for both HUD and mirrors) and sequential mirrors option unchecked and like this I can get stable 120 fps (vsync limit & monitor refresh rate) while in flight however it does dip a bit into ~80-100 fps over large cities/forests... I think I haven't seen fps dip under ~80 or so which is ok by me. Mind you I also increase render distances for shadows as well as shadow map to 8196 in shadows.lua file (which is why my fps is bit lower over large & dense forests).

Thanks for making this into reality ED!

So it seems, but it was with the resolution set to 1024 (personal preference: I’d rather have no mirrors than pixelated ones).

Before the restart of DCS that was apparently needed for the new mirror options to work properly, turning on mirrors cost me 1fps. When I tried yesterday, they cost me 10fps, the sequential rendering didn’t change anything.

So I turned them off again. They did look good at first glance, but the performance penalty wasn’t worth it for me. I hope that when we get Vulkan (if I’m still alive by then) there will be enough performance headroom to enable them again

I messed around with the settings a little more today.  It seems that you are able to tick the “every screen” and the “ sequential mirror” options within the game.  They take effect live.   That’s how I was able to verify that checking either of those options causes the frames on the mirrors to drop significantly.  

I have both unchecked, and the mirrors are nice, sharp, and run at good fps.  

Maybe these options are better suited to flat monitors, because in VR it’s very hard to ignore that your mirrors are lagging.  Either that, or the options work relatively better if you have a really slow computer.
