FS#3466 - Extreme lag when facing many or certain entities
Reported by Peeg:
As soon as there are many entities on screen FPS drops to a minimum.
It’s very noticable in crowded guild houses (<1fps for me) or the camp on bdroad2 (<5fps).
This has been a problem before, but it got way worse.
Addition by Lanarel:
There seem to be different things causing extreme lag. The number of items may be one (as loading continues for several minutes in the background), but also complex maps (hydlaa, with many objects), complex lighting (such as campfires), and possibly particle effects (although the flames at the temple do not seem to slow things down for me much). And portals, which always give a huge drop when they come into view (even if hidden by rocks, such as the corridors in the *road maps).
Talad did already some testing with grouping objects (e.g. buildings) and setting max distances on effects. I assume doing the same on portals will also help a lot. I do not need to see the portal to the top of the tower or the road to the magic shop when standing in the plaza, but I definitely lag more when looking in that direction (more even than the general high part of hydlaa with all its buildings).

Reason for closing: Will not fix
Additional comments about closing:
Will not fix in PSLegacy release, check
PSUnreal release.
Is this still a problem? I remember having this when rc2 came out, but after a bunch of updates it seems to have mostly gone away. Particularly, I think a newer CS helped.
I observed this problem earlier today. Interestingly, it seemed to be doing lots of time in the culler; Xordan's bounding box stuff for instancing seems to indicate that items will never get culled.
But I can't reproduce it tonight, even in the same place, so I don't know. Every time I see this it seems to be something different and randomly goes away.
I have had several player petitioning about this kind of lag. Mostly around the explorers camp and camp banished. Related to campfires?
Try renaming art/itemeffects.xml (so the client won't find it). That should fully disable campfire special effects.
I can confirm the issue around the mentioned explorers camp. The game freezes for 5-10 seconds there.
I don't know it is helpful or not, when i experience such lag/stop/freeze the game writes on console rows like these:

Could we have an update on this one please?
There has been a lot of changes since 0.5.
Also, provide your hardware specs.
On my side, the problem at the explorers' camp seems mostly related to the to campfires there, not the number of entities:
- Without (art/itemeffects.xml renamed, as suggested by Kayden) fps varies between 45 and 70.
- With campfire enabled, fps varies between 20 and 30.
That said, it has improved a lot. Before 0.6, fps used to be lower than 10 there with campfire enabled.
As for facing many entities (like in the red crystal den, for example), compared to 0.4, I didn't notice any worsening during 0.5.

In Hydlaa, close to fireplace, and looking towards Harn and other players moving around, I drop from 110fps to 22fps. (If I then use some magic, it still stays on 22fps (no further drop))

Win32, BGLoader = Models: There are still places where you get extreme lag while moving or just turning around. The most obvious area is the right-turning corner out of the arena tunnel (Old Quarry Road) towards the Hydlaa plaza. Still rather obvious is the whole plaza when walking forth and back between Harnquist's forge and the staircase up to the Highwatch.
The new and improved Background Loader is indeed much better, but the game still hangs while art is loaded out of ZIP archives. I did not yet compare different compression levels, though.

Running around the barrel racing track near the Explorer Outpost lags only sparselny now. But entering the outpost was able to keep me locked for ~15 seconds - for the first time; the second time it was nearly smooth.
