Map Performance

[Beirut]

Just did another bunch of runs, touch and go at Mount Pleasant, bop over to Stanley, all kinds of altitudes, then rooftop over Stanley, and the only consistent thing I noticed is the the Phantom hurts the most. FPS hits between 30% and 50% over the same spot on different flights.

 

In the F-18, it's almost always a 10% hit at most, once I got about a 30% drop over Stanley, tore past, went up, went down, turned around, came down, and got a 10% hit in the exact same place and altitude over Stanley except this time I was going the other direction.

 

The Phantom is the only consistent FPS killed with me. I'll try some more on the mainland. What a gorgeous map!

Have you tried any of the radar performance settings in the Phantom?

Not really. I can count the A2A missiles I've fired in the Phantom. I'm all about the A2G.

 

But if you have a recommendation, I'm happy to hear it.

Right! I tested myself on the newest update. You guys are absolutely correct. Up above I get steady 60+ FPS, and going down low it drops to a steady 19FPS. It wasn't like this for me when the F-4 initially dropped. For good measure I tested Kola, (damn those textures really looks like winter here in Norway, with a couple of flaws). Steady 45FPS medium hight, guess the trees take a toll, and going down low it fluctuate, but not less than 30FPS. So, somethings up with the SA map for sure.

But as posted, I was only getting the FPS hit on the SA map with the Phantom. I lost 10% with the Hornet or Eagle, but 30% to 50% with the Phantom. I'll fart around a bit more and see what's what.

The only thing I'm noticing with FPS hits that is consistent are the inconsistencies. This time over the mainland, up and down in the altitude, valleys and peaks and very low level.

 

I get a 10% hit going going west, turn around and I get a 30% hit over the same place going east. Most planes drop 10% at treetop then the Phantom drops 30% and then another plane that dropped 10% before now drops 30% and then the Phantom drops almost nothing at all at very! low level. Though the Phantom still tends to get hit the hardest.

 

It's like rolling the dice.

[Biggus]

That's probably part of why it's hard to diagnose and fix.

I get the issue in VR with the mossie and the F-14 as well, so it isn't just the F4 triggering it. 

[MAXsenna]

Did some testing tonight. F-4, F-15 and Kiowa get this strange slowdown, but not the Mirage F-1 as far as I could tell. Testing more tomorrow.

Took the Mi-8 out to see what was what and go more inconsistencies. A 10% drop here, a 30% drop there, and then a 10% drop where the 30% drop was before, and so on and so forth.

 

Only sure of two things: The Mi-8 is awesome and the SA map is gorgeous.

True and true!

So briefly I thought @Holbeachs workaround of reducing gpu load by reducing the aircraft textures was going to work for the mossie in vr. Untill it didn't.

Then using his latest .miz file I thought he had performed some wizardry because for the first time ever the F-14 was faultless over port Stanley. But after flying for a long while then exiting and restarting the miz it finally failed.

Then once that had eventually failed, I was able to replace that plane in the mission editor with every airframe I have and they all failed. Even the 'light load' aircraft that I thought did not have the issue. So now I am dispondent.

All I can report with any certainty is that the problem does occur in the following modules in VR:

Mossie, F-14, Harrier, F-15C, P-51, Ka50, Hind.

With typically 30-40fps at med alt over port Stanley dropping suddenly with that fps step to 11 fps at low alt.

As mentioned before.

Tried it now, and it has completely removed the 20FPS below 900' for me. I do get stutters and slowdowns here and there, but not like before, and it quickly catches up back to "normal".

Cheers!

Read the install info and nearly had a mental breakdown. Maybe this will get into an update at one point.

Just to share my long and bitter experience guys, but I'd recommend avoiding concluding that you've managed to eliminate the bug in module x until you've spent more than a few days testing it.  Full system restarts, mission reloads, flying a few missions on other maps and then returning to SA, etc.  I've fallen into the trap of concluding that the bug has disappeared or  module x does not seem to exhibit the issue, only for it to return in the not-too-distant future.  There's a random element at play.

If you're experiencing the bug, please add to one of the bug reports.

 

@MAXsenna does that mod pass IC?

Think I have to go with Biggs on this one. Keep using it for a while and see how it goes. I turned my textures right down to low and thought that was a fix even in vr. (Which should be way more aggressive than 'optimised') Then 20 mins of use later.....

Don't just turn textures down, turn default medium or low on, that's what I did and it immediately cured the problem.

Unfortunately it doesn't seem to work for anyone else.

It looks horrible, but if it works then you can start increasing stuff until it fails again.

I'm still 100% clean using this mission every day.

Settings. Vsync fast. Max frames. 13 Yo pc.

 

 

Falkland AA (3) mission WIP.

Start Stanley F4 54fps, Priority 2 Bears. They will destroy your fleet.

6 MB 339 will destroy Chinooks at San Carlos and Goose green.

2 x 2 F1 will destroy aircraft parked at Stanley.

2 Viggen will destroy Rapier site at Stanley.

Damage limitation is up to you.

Would be very interesting if you tried reduced textures with high on. Then we would certainly get some sort of benchmark.

Yes, I tried all settings adjustment from High,, using a simplified version of Falkland AA mission right from the start, running repeat missions for about a week with no luck.

Then I used preset Medium and bugger me the 900' ball drop went away.

I then increased all values one by one and it was still OK, until I put 'Unit Texture' from medium to high and my ball drop came back.

Back to medium and it went away. Increased all other values to what you see in the screenshot and I've been clean for 20 days, with 100% success rate.

Unfortunately it doesn't seem to work for anyone else.

Not what I meant, this on the other hand, and keep your settings on "High".

And best applied with this.

Thanks, but that's not for me. I don't mess with inner workings, that's what I expect the Devs to do.

That's cool. I just advocate for more users to try this, to get some traction that might get ED to have in their hearts to reconsider how they develop their modules. Not everyone can purchase a new computer every second year. The process is quick, and ED could probably fix this in a matter of days. I'd propose the new textures as "high" and the original oversized ones as "Ultra".

Yeah. Most of my settings are already way lower than the medium settings you are using in your screen shot. I'm sure I could neuter dcs to the point where there was so little load on the gpu that the problem did not trigger but the result in vr would be truly awful. 

Unfortunately I'll just have to fly the maps that actually work and hope this will get fixed one day. It does explain why there aren't many missions posted for this map. Which is unfortunate cause I love how it looks.
