[REPORTED]2.5.6 Performance

[30mikemike]

 

 

Really you should only be using one form of antialiasing at a time. MSAAx4 with MFAA enabled looks better to me and costs less than SSAA at 1.5 or 2x. Mixing antialiasing results in significant performance loss. The only one that makes sense to combine would be FXAA, since it has a minimal performance cost, but I don't like how FXAA looks and leave it off. MFAA basically reduces the cost of MSAA by 50%, so MSAA x4 with MFAA enabled has the performance hit of MSAA x2.

I have read various posts about mixing both MSAA & SSAA but to be fair I’ve always found it fine. I have to maintain a constant 60fps for TrackIR and my current configuration and in game DCS settings allows me to do that. Although since the arrival of 2.5.6 I noticed that I couldn’t run MSAA x2 & SSAA x2 (as I did in 2.5.5) as it dropped the frames slightly below 60, hence me dropping the SSAA to 1.5.

Interesting read though mate and I’ll definitely give your MFAA method a try.

Make sure you have SSLR and MSAA off, they are frame killers, after that try with shadows off or reduced.

 

I have a new machine now, and performance is great for me, it is obviously a pretty beefy machine, but I am getting a solid 45FPS near the ground and 80+ in the air.

 

 

 

Those settings are pretty low.

Why should I have to go backwards & diminish my gaming quality & settings from what I have been running for the last 12 months or so :noexpression:? 45 FPS on the ground is still lower than what I was getting before the latest updates. I was getting a solid 50+ FPS on the ground & 75-90 FPS in the air.

Now I get xPlane 11 performance in OB. Its very disappointing :mad:

I'd love to know where you got your 10900K. Impossible to get AFAICS in the UK. Been trying for weeks now!

Could you tell me if the performance difference between single and multiplayer is big?

[Lanzfeld113]

Yes

[Shadoware]

How much big?

[speed-of-heat]

Multiplayer is typically more ram intensive. You need 32 rather than 16. It can also be more gpu intensive, as higher volumes of players in close proximity tends to require higher rendering... it can be be more cpu intensive depending on a number of factors.

 

So to answer like a fighter pilot... “it depends...”

Talking about your system, if you get around 100fps(in a certain game setting) in single player you would get how many fps in multiplayer?

Its not really measurable like that there are so many variables.

If you are getting 100fps in SP with a good amount of units then MP should be ok for you.

You will just have to give it a go.

Its like speed-of-heat said “it depends...”

Visbility Range to High

Shadows - > Off

SSAA -> Off

Chimney smoke -> 1 or off

 

should make the world of difference to your perf...

 

Tried your settings small improvement in stable no improvement in OB. :cry:

[speed-of-heat]

you need to restart DCS ...

[mrmat01]

:huh:

Restarted DCS, Restarted PC, Restarted Patience, :noexpression:

Sorry mate doesn't fix it. Its broken ED need to fix it.

But I don't think they quite know how just yet. :doh:

I'm sure there working hard on it. :joystick: :helpsmilie::confused:

I just wish it hadn't got to this state. :cry_2:

[utplayer01]

Hello,

Sinse the new OB comes out i have trouble with 2 things. First... If i start my DCS i get a message that FC3 will be disabled. Why ?

 

Second... Next problem is that i have many Framerate drops since the new OB Version... thats really uncool...

 

I hope this problems will be solved soon

@mrmat01: I think your issue has not much to do with the performance issue of version 2.5.6. I suggest you create your own thread here: https://forums.eagle.ru/forumdisplay.php?f=445

 

It will be easier for us to help you.

what are you actually seeing in FPS, how are you measuring this ? are you in VR ? if you are in VR you will most likely have ASW or Motion Vector Switched on, you will as a result see 45 fps , or half of what your maximum frame rate of your HMD is going to be ...

 

I wont say that 2.5.6 is the same perf as 2.5.6 but if you dont see any difference in frame time in VR or absolute FPS from 2D switching off shadows ... then i would suggest something else is amiss...

My point. That is why I think a new thread is necessary to address his issue.

Seems nothing more then a placebo effect to me. Never seen any improvement by deleting them and let them rebuild.

Hi mate

I do not use VR!

I'm measuring the system performance with MSI Afterburner & the generic FPS counter in DCS.

This is only happening in the OB. My stable install is running much much better.

 

My PC specs

 

Intel Core i7-8700K @ 3.7GHz

16GB DD4

GeForce RTX 2060

Track IR 5 running 1440p @ 144mhz

on a 32" curved MSI OPTIX MAG 321CQR

Dedicated 500gb SSD

 

OB was a brand new install on a new SSD the day the Supercarrier came out. I was getting fantastic performance 50+ FPS on the ground with a fair amount of units 45+ on the Supercarrier with a busy flight deck.

This was pretty much the same in all aircraft on all maps except the channel map.

In the air I was getting anywhere from 75-100+ FPS. As high as 135 over water with units around me.

A few weeks ago now after a update or two I only get 5-15FPS on the ground & in the air.

The only variable in all of this is DCS & the updates. Good before bad after.

I can not explain it any better.

Nothing in my settings has changed my NVidia drivers are up to date. There isn't a issue with my hardware.

I know this because all of my other programs/games run run flawlessly with very high FPS.

Hi

What are they?

Why do I need to delete them?

I have never had to do it before for any program.

It's not about any improvement. The shaders need to be rebuilt and it is a requirement that the changes take place at all.

 

C:\Users\yourwindowsaccountname\Saved Games\DCS.openbeta

 

Find 2 folders named: fxo & metashaders2 and

delete them every time you change settings. There may be settings which don't need the shaders to be rebuilt, like civilian traffic, but I would always do it just to be safe.

Did I say "VR"? I did not.

 

I said that your FPS issue is obviously too severe to be the sole result of the last open beta updates. The truth lies elsewhere, and I think you should open a dedicated thread to get some help.

problem with stable release performance

 

Hi guys

 

I'm writting here because i'm having lots of problems with the stable version of DCS.

 

After a month without playing and of course updating my DCS I have had to reinstall the OS (Windows 10 pro 64 bits) because my 10 years old HDD finally died into a new 1 TB ssd and reinstalled again all the graphics drivers, and a new fresh stable DCS version.

 

My problem is that while before the new OS and DCS reinstall I had stable 40 FPS in VR with my system, but now I can't manage to get even solid 30 FPS making some campaigns completely unplayable.

 

I've deleted the metashaders 2 and fxo, repaired DCS, updated Nvidia drivers and nothing seems to work.

Maybe I'm one of those folks to whom the 2.5.6 update ruined everything and have to wait for fixes or I've missed something, that's why I'm asking in this thread

 

Thank you very much in advance

 

My system is the same than in my signature, apart than having the OS in a new SSD.
