[CHK] FPS Issues with JF-17 Cockpit

[paco2002]

Hello all.

 

I've been flying the JF-17 since day 1, and I never had this FPS issues with the Cockpit, the big issue was with the last update of the Cockpit, that just ruined my FPS and experience.

May I ask for a solution? Or a quick fix? Maybe a way to roll back to the older cockpit?

Not sure if that's posible, but just letting you know that there are some FPS issues with the latest cockpit update of the JF, loving the plane!

 

Thanks Deka Ironworks!!!

(I'm in VR)

Please, delete this thread, I think it's not in the right place. :doh:

it's in the right place if you report any issue

please attach any screen recording to show it

no report from others so far, and i cannot reproduce significant FPS drop

also we haven't changed any cockpit model

edit:

i don't have VR either....

I don't feel any FPS hit, but I don't have VR in hand, so the experience maybe different.

Here you got the screenshots, note the JF is turned off, and is a really demanding plane when you tuned it on due to the screens and all the lights it has.

In VR fps are really important, when FPS vary in VR the user can suffer sickness, and thats not Good:(

Other planes Works with higher FPS, that's why I speak about the cockpit, because I think that there's the problem.

 

PS: I know that FPS may vary between aircrafts, maybe something between 4-5 FPS, but having 10, or even more than 10 FPS difference is quite a hard hit in VR.

your screen said "out of focus" if dcs is not your focus app, your fps will be lower

I know it's out of focus, and, at least for me, it doesn't lower my FPS :doh:

I have extreme fps loss when turning on AG radar. Using free flight instant action I go from 75 fps to 15. Just a datapoint for you guys.

 

2.5.6 is a complete mess, so I imagine it's not a deka issue per se, but it is a problem nonetheless.

 

All graphics low/off except:

Textures: high

View Distance: high

MSAA 4x

Cockpit Display resolution: 1024

AG radar use shader, it DO hit FPS when turn on or aggressive maneuver: scanning new terrain.

Just to be clear, this problem for me is new to 2.5.6. I had no measurable fps loss in 2.5.5 at all. Also, the fps doesn't just tank when turning on the radar initially or during a maneuver. As long as the radar is on, the horrible fps is there, even if just flying straight and level (minimal new terrain processing)

 

Hope the information helps!

I've been doing testing, and I think the issues are on ED side, not on Deka Ironworks team hand…

Every one of us we're fine befor the 2.5.6, but with the 2.5.6 patch the issues appeared.

[mtd2811]

I see my jeff cockpit stuttering and losing fps also since 2.5.6 actually with other issues and general performance

 

So i blame ed for that not Deka

Personally I am experiencing a massive FPS drop when using the center MFD for anything requiring a shader to work; WMD Pod or A/G Radar. Only since this patch, and weirdly enough I have zero issues putting them on the side MFDs.

 

 

Sorry for being anecdotal, hopefully it helps somewhat identifying the problem, if it is indeed module specific.

Hi,

Could you try attached device_init.lua in SP and see which MFCD with AG/TGP etc turned on can cause massive FPS drop?

 

download it and put the file to Mods/aircraft/JF-17/Cockpit/Scripts/

device_init.lua

[Sangusan]

Using your .lua file the issue remained the same (albeit only in MP), with what I thought was a "workaround" no longer working; no matter which MFD I put it on, FPS would tank a tremendous amount.

 

 

 

That said, I think I solved my issue:

 

 

I turned off G-Sync for DCS in Nvidia control panel. G-sync, the way I understand it, compensates for low fps. Thing is, in SP my FPS are basically never below 80; it's just not very demanding in most cases.

 

 

In MP however (in this case the hoggit servers) my FPS average around 40-50, which makes G-Sync inclined to try compensate. I'm assuming (a lot, I know) it has some weird interaction going on with the MFDs that causes it to freak out: When the FPS drop happens my GPU usage drops to about 40% from its usual 99-100%, and upon turning the MFDs off it hops back to normal.

 

 

TL;DR: Turn G-Sync off and report back on the issue.

 

 

Edit: Well, turns out the ground radar still murders my FPS, with the exact same symptoms as described above (GPU usage dropping down to ~5% even). Sorry for giving hope. So far still exclusive to Multiplayer.

Big FPS drop when turning the batteries on for me, no VR.

 

 

Its weird, its only when the warning lights are flashing. I get 60 fps, then the warning light flash it drops to 30, they turn off it goes to 60, etc etc...

 

and when all the warning lights are turned off and the plane is running, its stay at 30 if I look in front of me, even if MFCD are turned off

I tried it as well and still tanks.

 

My game even froze when i turned ground radar on (in mp) and had to kill it in the task manager

Same issue here; frames tank in MP with AG Radar but my game drops to 1-2fps when turning on the TPOD in MP (vr). Happened multiple times to me now since the last update

[Sangusan]

I will leave you with this comment: https://forums.eagle.ru/showthread.php?t=256850&page=3

 

 

Apparently it's Datalink related. When I did my G-Sync testing I must have forgotten to turn Datalink on, and thus had no issues.

Massive Frame drops in A/G mode. Happens even if AG radar display or TPOD display is not up. Its worse when TPOD or AG radar is up.

I can confirm. This same condition lead to stutter and paused then crashed in MP. I tested it on SP but only had momentarily stutter when switch to AG Mode but went fine. I suspect it AG radar need to be optimised ?

[paco2002]

The radar uses ED API, and is still WIP with the Ground radar. Maybe is something related with that.

So we know if ED changed/modified the API with the latest patch?

I think they doesn't share changes in API.

[AeriaGloria]

They use ED API. He static detection we just got was probably an update from ED on the base API
