Map 20 of AV loading problems with latest stable

gary · 2013 Jul 26

Even without any addons, if you load the map, it takes a long time, and if you try to reload the map after saving, it says 'loading' indefinitely and forces me to enter task manager. Also when I leave the game, I noticed recently that the screen almost fades to complete darkness, but takes several seconds to completely exit unlike previous versions, but when exiting the game form this map, it wont exit after fading, so I must exit through task manager here too. Maybe this map has a problem with Doomsday? It also seems that loading maps in general take longer then the last stable 1.10.

This is a known issue that we didn't get around to addressing before the stable 1.11 release. It doesn't actually get stuck, it will shutdown, however, it just takes a while depending on the size of the map...

The reason for this is a change in the management of memory needed for the bias lighting model and which presently uses a less than ideal algorithm to release it when the map ends (or you exit). Similarly it takes a little longer to load very large maps.

These issues have already been addressed in a work branch, however. We decided not to merge this work during the candidate phase due to the large number of changes involved (which would have delayed the stable release further). It will be merged soon, though.

I'm on map 25 - Demonic Hordes, and if dynamic lights and models are enabled, the slowdown is so bad that it is unplayable, but when I go to the console and shut off the 3D objects and lights, it is much smoother. Can you see how slow it is for you? Maybe we can find out why Doomsday is acting like this on this particular map. It acts this way on startup of the map. I am using #948.

Vermil · 2013 Aug 7

AV Map25 features 1325 bad guys, a huge amount more than most maps; Dday has to constantly monitor the AI of every one of them.

Try typing 'kill' in the console, to kill all the monsters on the map and comparing your FPS after, for instance.

I wonder what would have to be done to the engine to run that smoothly. :P

Edit: I used the command and it is still about the same. Doesn't change frame rate

Vermil · 2013 Aug 7

When I tested things, I tested while in the first couple of rooms and found that killing all the monsters did allow me to achieve near flawless performance, in those rooms.

But upon going back and exploring the rest of the map, I can see the FPS is still poor in many areas.

gary · 2013 Aug 8

Yeah, I played more of it and it does seem that the number of monster affects performance at the start. When first starting the map, it is unplayable with its low framerate (less than 1 frame a second) but if you deactivate 3D objects and lights, it runs fairly smooth, though a little choppy, but once those monsters in the big room all start warping in, it will becoming so slow that it's unplayable even if 3D models are not active along with dynamic lighting. With the 'kill' command, it speeds it up again once you reach this point, but still choppy as long as you have 3D objects and/or lighting activated.

When I played AV for the 1st time almost 6 years ago, I don't recall this map being as slow because somehow, I was able to kill monsters as I progressed throughout the map since I never cheated. That was back in the days of 1.9.6 - beta 5. What has to be done to the engine in the future to make the game accept so many monsters without any slowdown, and also make it so having 3D objects and lighting not slow down any map? Besides a lack of OpenGL 2.0, what else is limiting the speed of Doomsday? Is there some reason why even though we are all the way to 1.11.1, we still encounter these issues with performance? And I know it has nothing to do with my hardware.

On a side note, I notice that anytime you switch into automap, framerate goes down, but put it back into normal mode, and it plays at its previous framerate

There's no secret to this: we have not been putting effort into optimizing the renderer as we're planning to overhaul it radically. Hence we've been focusing on other components.

It is easy for us to determine the bottlenecks in any particular map using a profiler. However, getting rid of the bottlenecks many times requires fundamental changes to some algorithms or data structures. Bad bottlenecks are for instance in the particle generators, model renderer, and the renderer's per-frame data structure updates that aren't really necessary to do every frame.
