Summary | 0005124: DR slow/laggy to move light sources around - on large maps | ||||
Description | This is an old bug - if you have to move a light source around or adjust its light radious - its very very laggy. Current work around is to select the light and/or the objecting near where you moving the light to and press shift-h then its smooth again. | ||||
Steps To Reproduce | - Open DR. - Go into Orthoview. - Select any light source (models or pure source) - press LMB and move the entity around | ||||
Additional Information | My guess is when the entity count goes above a certain paint DR is running into some kind of issue, that causing the lag. | ||||
Tags | No tags attached. | ||||
Is it possible to know whats causing the lag, or is it just not realisticlly fixable..? |
|
There's a lot going on when manipulating lights in large maps. It's due to the way DR is keeping track of lit objects, which is in fact very inefficient. It can be fixed by changing the way it's done, but of course this is not exactly trivial. |
|
Well the work around I have for this is to press 'shift-H' to hide everything bar the light and or model I am trying to move around. | |
@Bikerdude, does this still happen in the latest release? In my testing with the Painter's Wife, I don't see any more lag dragging a light around or adjusting its radius than any other object, at least in regular 3D fullbright mode. In lighting preview mode it is very laggy (as low as 2 FPS) but this same low framerate appears when just moving the camera around, so it doesn't appear to be a specific problem with lights (and we know the lighting preview mode is horribly slow). There were some significant architectural changes made to light handling in recent months, and I am wondering if this might have unintentionally fixed this issue — in particular, if you are not using lighting preview mode (which most mappers don't it seems), there should be NO lighting calculations whatsoever. |
|
Well whadya know, I selected a bunch of lights, brushes, models and other entities and moved them all at the same time with no lag. And this with ALL of the map layers visible...!!! In 2.8 I can't even move one light. I have asked Dragofer/Amadeus to confirm, but I would see this can be closed :-) |
|
I haven't had issues with moving lights in that map on any DR version, so wouldn't be able to confirm that anything has changed. Always worked fine. |
