LZDoom 3.83a 10/27 released

[Kamil]

All the same problem. It is strange that new versions of GZDoom do not suffer from this.

Could you please try with JIT disabled (+vm_jit 0 from the command line)?
Are you using the latest GZDoom version? Did 3.82 crash?

[drfrag]

It's fixed. I've retired the release, i could not download the huge mod (near 400 MB!) yesterday. It was an old bug fixed during the Level refactoring, a bad NULL return value in AActor::StaticSpawn. Very unfortunate, there were reports of PB being unstable at Doomworld with older versions of GZDoom (edit: it was fixed in 4.0) but since the mod gives a wall of errors i didn't pay much attention last night. Later i'll upload 3.83a.
Thanks Kamil for the reports!
Edit: today's devbuild shouldn't crash. https://devbuilds.drdteam.org/lzdoom/

I checked a new test build. As long as there were no errors related to PB, but for some reason there were serious performance issues.

[drfrag]

Performance should be the same as in 3.83, do you mean now it's even slower? I see no difference here.

Upon further investigation...
@realdevs: Houston, we've got a problem. AFAIK in master AActor::StaticSpawn now can't return nullptr since "the final batch of easy level replacements" (uses the auxiliary ConstructActor procedure) but there are still several null pointer checks (searching for '= Spawn' in p_mobj.cpp). There could be actually a minor performance regression.
May be i should add the missing null pointer checks here.

[drfrag]

I've reverted the commit and added the missing null pointer checks, so it was not a bad return value. Performance is as shitty as before tough.
@Kamil: thanks for your help again.

lzdoom-d-x64-3.82-122-g55af0b11c.7z dated September 21 was the best in terms of performance at the moment

[Kamil]

By the way, lzdoom-d-x64-3.82-140-g8227e795c.7z dated October 4 is also very good with performance

[Kamil]

I tried a new build of LZDoom. All is well with performance and PB. But you can’t configure Nash Gore in PB 3.0 in any way you want, otherwise the game will crash. GZoom has no such problem. And I noticed that Direct 3D is faster than OpenGL. I use the maximum settings.

[drfrag]

What setting did you change exactly?
The -d- builds are those i compile myself but they are not Release builds. The last one contains a half-assed feature and then i did a hard reset. Later i'll upload another one with the fixed tall skies in software and the new command to unset the quicksave slot.

Thanks, that's certainly a lot of info. For me it doesn't crash changing the Nashgore settings. Did you load something else besides PB?

[Kamil]

No

[Kamil]

I didn’t download anything else. And by the way, why aren't you in the Discord group?
