I have an empty mission single spawn where fps is a steady known value. Switching to the video page fps drops 5-10 frames which is expected as its another viewport render.


Changing to another page however does not recover the fps lost.  Going back to the video page and selecting no video regains fps lost and returns to the known value.

 

Appears that the viewport is still being rendered in the background when no longer displayed.

That's normal, if you don't select no video whatever video you're viewing will be displayed in the background of other pages. I also experience FPS drops when using VID or TADS.

Yes but in my case it was switching to a page that did NOT display the video in the background.

 

The video image was not displayed in any way and yet was still being rendered in the background, background meaning application code not visually.

Can you send a screenshot? It's not going to show the video symbology when there's an overlay up if that's what you're saying, would be easier if I could see what you mean

Go to the video page and select TADS.  Then select the TSD page with the map displayed.  The video is no longer being displayed to the user because the map is now displayed.  However by looking at the frame counter you can tell the video texture is still being rendered on the gpu in background code because the fps loss is still present.  Switch back to the video page and select "No Video" and then go back to the TSD page and you will see that the games fps has gone back up to the value before you ever selected a video output.

Ahh okay I understand what you're saying. Yeah that shouldn't be happening.

I don't see what a track file would provide. Its not mission or map specific.  You would need my computer to replicate the problem or tweak your settings to a level where toggling a viewport on/off produces a fps hit thats noticeable.

It is known that a targeting pod at the code level is a render viewport which in any game/application incurs a fps hit.  Its rendering the scene an additional time.

In this case when switching to the TSD page with the map its not toggling the viewport rendering of the video off.  Off as in at a code level not a visible to the player level.  All other pages will display video as a background so its easy to see how it could possibly be overlooked.

This is a ask the devs if the page selection to the TSD toggles the viewport rendering on/off the same way as when you select "No Video".  Because it appears at the moment it doesn't.  Which as stated can be an oversight because all other pages will show the video as an underlay.

  1. Get your game settings to a high level so that turning on a 64 sensor produces a 10ish fps drop
  2. In a hover on any map write down your fps
  3. Go to the Video page and select TADS as your video source. 
  4. Select the TSD page with the map visible notice that fps does not increase with video no longer displayed
  5. Select video page and "No Video"
  6. Select the TSD page with the map visible and notice fps has returned to its value noted in step 2
