Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

[Request] Ability to downscale viewport resolution

Hi,

I am running the editor on a fairly high res monitor. The problem is that the monitor is too high res for my video card to handle a very fillrate intensive app like the unreal editor and hence the framerate in the viewport is quite choppy. In order to fix this I need to make the viewport really tiny or I have to change my desktop resolution which makes everything else big and ugly looking. It would be great to have the option to downscale the viewport resolution by half (while maintaining the actual physical size of the viewport) or something along those lines so that I have a decent framerate while working. I get an average of about 30fps right now in the viewport but it becomes worse as more stuff is added to the scene.

did you tried tweaking the "screen percentage" value on global post processing volume ? http://img15.hostingpics.net/pics/705353104054245609072230402014032300001.png

or the resolution scale in the quick settings (better) ? http://img15.hostingpics.net/pics/692014104054245609072230402014032300002.png

that could be some fitting solutions for the moment :p they are more accurate solutions explained in the official documentation as some people told me but I didn't started reading it for the moment, I'm gonna start tomorrow.

You mean for example, play in 1920*1080 but render the scene in a lower resolution to save GPU processing ?

Yes, but even while editing. What I mean is if you are running the engine on a high res 4k monitor and your desktop is running at the native 4k resolution, if your editor viewport (the part which does only the rendering and not the ui panels on the side) takes up half the screen space, the resolution of the viewport is pretty darn high almost full hd. It would be great to have the ability to reduce the resolution at which the viewport is rendered. This would allow the user to still make the viewport take up half the screen space but make it run at a higher framerate. I am running it on a mid range gpu and the only work around for this is to reduce the desktop resolution to something like 1650 x 1080 (this would reduce the resolution at which the viewport is being rendered as well). But this causes the text and everything else to be much larger and you lose real estate on the screen.

Thanks for the response, I just tried that and it seems to work only when you hit play and are ingame. It does not change in the editor viewport when not playing unfortunately. It does exactly what I was looking for but only in game.

I didn't find any option to downscale editor's resolution. Maybe if you extend left and right bars you can have a more little rendering space in editor view, I know resolution and aspect ratio auto adapts to that.
