[REPORTED]FPS sometimes hit hard while in a F/A-18 C

While flying around in the Hornet i noticed that the game sometimes stuttered slightly in the same way as it would do when the FPS dives below the VSync threshold.

So i took the FPS counter at hand and yes, my assumption was correct. So i did comparison test between the F/A-18C and the A-10C.

Created a test mission, landing at Kutaisi and then after landing taxi to the end of the runway and there turn left, taxi halfway, stop and look left.

The mission contains nothing but one non-loaded aircraft and for the rest plain DCS World, no extra objects. The difference between the two is the object count for the same mission, same world, only different aircraft.

A-10C Landing: FPS = 143

F/A-18C Landing: FPS = 124 (so a difference of around 20, object count in this view is +/- the same).

A-10C Taxi: FPS = 124 (the object count here is around 400).

If i look forward, the FPS still sits around the same 124.

F/A-18C Taxi: FPS = 56 !!! (the FPS drops right to below 60, if you wait a bit the object in this spot goes up to 1800 !!!

so the difference is the object count which has a hugh impact on FPS, the difference between sitting in the A-10C or the F/A-18C is almost 70!!!)

If i look forward here, the FPS rises up to around 72.

Now, in the images before touching the ground the difference is only +/- 20 FPS, however once landed the difference goes up to +70 for the same spot.

Why?

Seconded! I noticed this same phenomenon and posted a thread about it here: https://forums.eagle.ru/showthread.php?t=220263

I have experienced similar in the past, but wasnt tied to the Hornet. Ive had it happen in the Viggen too. Doesnt happen every time either for me. Happened to a friend of mine too.

And after a rearm/refuel and taking off, fps would be normal again.

I noticed this too. I think that the WIP nature of the Hornet has something to do with it.

It happens to me when in certain places in Caucasus though not sure if it's something elese...when near kutaisi, there is a spot that seems to cause that drop, when I fly in a different place its gone...

Ffs moved to game performance again?!!! This is a hornet issue only for me.:mad:

The scenario described by Lange_666 is known for me every time I land in Novorossiysk for rearming and refueling. Recently I got new rig and every single module (exept Mig-21) runs really nicely in VR. I hoped to see some improvement regarding to FPS drops and stutters I experience after landing the Hornet but, the problem seems to be more related to game code as I see. Just to let you know, the game in VR becomes almost unplayable after landing.

P.S. Thread should be moved to F-18C Hornet section not A-10C...

LOL yeah they moved it to the A-10C performance. LOL.

Clearly didn't read the post because there's nothing wrong with the A-10C.

ADMIN please stick this back into the F-18 BUGS FORUM. Its related to the F-18.

I hear you guys! I have a huge performance drop in the Hornet. Especially if shadows are on.

Bump - please move this back to the Hornet bug forum where it belongs.

Lange : I suggest you swap the order of the images so the Admin sees the Hornet cockpit first and doesn’t instantly assume it’s a Hog issue.

It's not limited to the Hornet - I've been experiencing similar massive drops in performance in and around airports. One mission it will be fine - then reload the same mission and the FPS drops like a stone until you fly away from the airfield.

JFC I've been flying DCS for 700 hours at 19-24 FPS. Is it really that bad when your frames drop from 100+ to 50+ ?

VR is unplayable (headache and nausea inducing) under 45 FPS so when you are at about 60-70 on landing and then on touchdown it goes down to 20-30 then yes it’s bad.:puke:

Thanks to the mod who moved this back to the Hornet Bugs Forum!!! :thumbup:

Oh well, I see it's a serious issue. I've experienced the same FPS drops as Vitormouraa. Huge FPS drop with shadows turned on (only low, but still big performance impact). With literally everything set to low and off (because I didn't know what else I could do, unless I turned off the shadows), FPS around 50-60 on the ground in the Hornet of course, on vJAG aerobatic server. After take off back to 150-170FPS. Actually the same is still happening on single player. Also as we are still talking about FPS in the Hornet. Recently for unknown reason my RAM usage went from 5GBs to 10GBs, causing really unstable FPS going from 90 to 20 every 0.5 seconds. Then RAM went back to ~5GBs and everything was back to normal.

FPS Display

I am new here so pardon my ignorance.

Where/how is the (FPS) data displayed? Is this data displayed in real-time somewhere during flight?

Thanks!

It displays in the upper left corner.

RAlt+Pause/Break is enough. The rest as Fisherman82 said.

Hornet vs Hog - 30% drop in fps on Hormuz in VR

Guys, I have this basic mission attached. Two planes at the same location. A-10C gives me 80-90 fps while Hornet 50-60 only. That is about 30% drop in fps. I'm just wondering if anybody else has the same result. Can you try it? Any ideas why hornet is so much more fps hungry?

Yep, I’m not happy about Hornet performance in overall as well. I’m having a lot of stutters after landing on airstrips...and not a single word from ED if the issue well know or not.

A-10C is a released product, Hornet is Early Access. Maybe it gets more improved during development

Might it also be an issue that we are comparing here a piece of software (A-10C) which was developed a decade ago against a fairly recent and ongoing development? The A-10C was built with the available hardware and technology in mind that was around at the beginning of this decade (or even slightly earlier). Hardware has evolved a bit in those ten years so I would expect you tend to build more performance-demanding software nowadays.
