F-5 (old, not remaster) performance drop in the latest patch.

[MoleUK]

I have been running spotting dot testing for a few days, typically with 200 aircraft at a time. Performance has been fine until this update just dropped, now it has cratered.

Hundreds of non-moving ground units don't seem to cause the same performance drop, and facing away from the moving air units doesn't stop the CPU from getting clogged up. So I assume this is the AI pathfinding / AI thread clog bug again.

Please try replaying this at 1080p.

Title update to reflect source of problem.

Replacing the F5 I was sitting in with another aircraft appears to solve the problem, at least if that aircraft has no radar active.

Either all the old tracks had the radar defaulted off, or this new performance drop is related to the F-5 radar (or any radar possibly) having to deal with excessive amounts of air units.

At least at a guess.

Luckily I actually recorded some footage of one of the tracks in the F5 yesterday and this morning. The radar was always on, so I would double check that nothing has gone wrong re: radar performance. I didn't see any listed radar changes in the patch notes.

I can't currently test it atm, can you try turning off the F-5E radar and see if that nixes it?

[FZG_Immel]

yes, I even tried on the ground before having electric current on the plane. same issue.

 

its the F-5E remaster which is the issue. NO PROBLEM at all with the F-4E for example.

 

Also, i just come back from the cold war server, and other players have the same issue.

very very odd thing

 

I just tried jumping in the F-5E in the online server and dont have the issue anymore. now its fine.

 

but offline not. I dont get it

Special K suggested this was due to core parking not being disabled.

While I disabed core parking quite some time ago, a windows update looks to have reset some things. I will check back later to see if it's still disabled, and if disabling it resolves the performance loss.

I managed to get time to double check, my cores are unparked. So it's not that, at least not on my system (5800X3D).

2.9.11.4686 MYT F-5E legacy FPS dropped to single digits in all theaters

Something broke F-5E

Already reported, both in F-5E and general DCS performance bugs.

Same issue with F5.  I elected not to upgrade.

I'm getting the same issue. The F5 has always run well on my system. One of the less demanding modules. Even the update ran well. Since the latest update I am getting very unstable frame times. I compared a run over the N2 map in the F5 with a p51. Both had similar CPU and GPU utilisation (about 65-70% for GPU). The p51 flight was very smooth. The F5 flight had lots of micro stutters.

I think it might be the new audio.  I get 90s in the briefing screen.  If I press fly it drops down to 10 fps.  If I pause it shoots back to 90s.

There isn't suppose to be new audio for the F-5.

I cant play online with the F-5E now (legacy i guess..its not the remastered).. game practically freezes or goes to single digit FPS..

 

However the flamming cliffs one works good

 

here are screenshots ..first of the normal F-5E doing 5fps and then i spawned next (same server same session same place and time) a FC2024 F-5E (bottom cap)
