investigating Low FPS

So…this odd.  I’ve been running DLAA/DLSS (performance or balanced) ever since it came out, because it was so much smoother.  The ghosting sucked, but it was smoooooth.

But DCS has been running so bad for me since the Hook came out.   Last night I almost decided to log off the server when people started spawning into Chinooks, just out of pure anticipation of frustration and nausea.  
 

Then it occured to me that I missed being able to read the displays in my F18 like I could pre-dlss days.   I figured things can’t get any worse, so I switched to MSAA x4.   Could you believe that stuttering I get when I’m flying next to a Chinook went away!?!?  Well, that’s exactly what happened!!! Crisp image, and no more weird stutters or constant image hitching when I turn my head with my Quest 3.  I even flew a little aerobatic dance in my Huey with a Chinook!

So now, MSAA (x4!!!) is smoother?????  How does that make sense?  My oh my, how the turns have tabled!  

There’s definitely something up with the current build, and I don’t think it’s the Chinooks fault.  My apologies to for casting any aspersions towards, what is likely,  a very fine module.   

By the way, I reserve the right to come back tomorrow and complain about crappy performance.  In the last couple of weeks I’ve celebrated victory over bad frames at least three times after applying different changes or recommendations.  All were spectacular successes (especially “run in full screen”) until they weren’t. 

So.. i am complete the opposite.  Until the Chinook release i was running MSAA x4 and everything was smooth... Now i need to run DLSS as MSAA is a frame rate killer on my machine and stuttering is horrific.

I run an i9 14900K, 4090 with 64Gb Ram at 6600mhz.....  @BIGNEWY says performance issues are with lower spec machines so why's mine 9and other high spec machines) suffering so badly with FPS down by 20-30%.  Its crazy maddness and so hoping ED fix and optimise for everyone.

Please note...  M/B Bios updated and i9 14th Gen Issues resolved using intel recommendations.

We are looking at some fps issues and will look at some more optimisations soon. 

thank you

Same for me, FPS divided by 2 using the CH-47, also notice a very long loading time when it loads the mission with 1 CH47, 1 AH64D, 1 NH90 and my personnal super high detailled mod (I'm joking about the high detailled).

after this last update i cant even fly the 47, can not get anything to load just freeZes up and crashes

Hi, I just discovered a high VRAM load while using the CH47. 

In comparison the AH64D

 5 patches since release and no attempt by the devs to bring the crazy texture sizes down in order to lower VRAM footprint.

I keep thinking of upgrading to a new computer so I can finally play DCS without having to restart two or three times, and so I can finally enjoy VR consistently every day.   But then I see folks struggling with top end 4090s.   
 

It would be easier if I could blame my own equipment!  As it stands, dropping a couple of grand on a new system doesn’t seem like much of a guarantee of consistent performance.
