MASSIVE fps drop after update to 2.7

Thanks to my friend @SmirkingGerbil I have settings that give me a steady 50 to 90 FPS depending on the scene. No stuttering or freezing except,

I have one mission on The Channel map with a "big formation" of B-17s that drop on the Dunkirk Airfield. When the bombs hit, my Frames fall through the floor.

In the picture below, I am at 17,300 feet over Calais which is 26.25 nm from Dunkirk. The picture was taken 2 minutes after the bombs hit and my frames were still down to 7-8

I would expect  a big drop like this if I was close to the target zone, but I was so far away that I couldn't see the bombs hit nor could I see the B-17's formation.

Is this normal, or do I have to tweak something else?

Good news - not sure if I have an answer for this, but in my Squadron, when we run "Operation DCS Liberation" - with a lot of AI activity, like on the TARMAC for take off, everyone experiences frame rate getting tanked. We are not sure if it is AI processes hitting our CPU's or what.

Not sure if related, but if the Bomb Drops, and the formation of AI B-17's are all mashing your CPU to do their calculations etc it MIGHT (and I stress might) be related? Others smarter than me can comment and clarify.

I guess my question then is, why do the frames drop when the event is not on the screen? I would experience this in 2.5.6 also, but

it would return to normal a few seconds later. With 2.7.0 it is several minutes to recover. This picture is after all 2 mins after the drop.

Empty mission in 2.5.6 (121 FPS)

 

Empty mission in 2.7 with clouds "nothing" (92FPS)

 

24% FPS lose

 

well ****. (i took out pictures for space). 
For me it is only the clouds that cause the drop. Thanks for showing this to me. I do not think that for me personally there is difference if clouds are set to 'nothing' in 2.5 or 2.7 but i guess for others there is.

I see much more stutter in VR with this week's patch

 

I was quite happy with the performance I reached with 2.7 in VR (despite having to downgrade settings again...) but it's all broken once again

I did as well. I changed SS to 0.8 and back to 1.0 and it was as before.

@MattCri

You are right and it has been write down here already few times. This has nothing to do with this clouds (or at least almost). I dont know why people still think its only the clouds.

Like someone write already, it is the maybe more the lightning or whatever they "messed up" with 2.7.

 

You can see on the screens the light and shadow is difference and i have same experience with that. (shadows was more "dark/powerfull" !?)

Not sure what looks more natural or better (maybe personal preference), but for me it looked actualy better with the shadow on 2.5 (not only on this sceens here, also at me)

 

Anyway, i have pur some settings down😐 and at least i have some decent frames on multiplayer but still not smooth and nice as it was before. Sometimes hard fps drops wich not happened that before, or at least i did not noticed because frames was high enough. So this hard cut/drops are most annoying for me at the moment.

 

Lets hope ED focus and invest some time and money in performance optimisation!

An observation about your statement of "same settings"

The graphics settings in 2.5 and 2.7 are not identical.

 

The most prominent changes which did not exist in 2.5 are the settings for "Forest Visibility, Forest Details Factor, and Scenery Details factor".

 

When you do apples to oranges between your two images, the 2.7 image shows softer edges to the forests, and more individual trees are visible - so this is not a "apples to apples" setting.

 

You would need to set the new "Details Settings" and SSAO! to match (if even possible) the old 2.5 settings for those details.

 

So it isn't really a straight up 2.5 better, 2.7 worse comparison, until you figure out how to modify new 2.7 settings to be as close as possible to 2.5.

i believe Forest Details Factor and Scenery Details factor, while not visible before, defaulted at 1.0 in 2.5.

Trees visibility is bit different, even on the same setting (i use 85%) and i agree 2.7 is a tad better.

 

 

Look, im not saying "2.7 is the same but much heavier" but for me, mostly because my gpu is a bit old, the increase in graphical fidelity is not worth the performance loss.

Well, that is good to know - I didn't realize there was a setting analog for Scenery Details factor - might be closer than I thought.

Wasn't trying to be heavily critical, I was going over the settings myself, and wondering how someone "could" do a apples to apples. I wonder if the devs could map it for us, or if it is even possible?

 

I didn't take near the hit some did, and the 2.7 screen is my current settings, with very little frame rate loss. Except for Syria, but Syria always loaded my machine in 2.5 and 2.7.  But I am Track IR, with 32 GB of RAM running from an SSD, with an SSD page drive so hard for me to say how much 2.7 really hit me and under what conditions. But overall my experience has been pretty good for the increase in detail etc.

I highly doubt the fps loss happening to some people (me included) in 2.7 is due to the new forest & scenery details factor settings. 

 

Because I have tested for numerous times that even when flying above an area of empty ocean towards absolutely nothing in front of me and no objects in my view. The FPS in 2.7 is about 30% lower than in 2.5. Also just looking up at an area of empty sky with no clouds, the FPS in 2.7 is also lower than 2.5. 

 

That's why I do believe there is something wrong in 2.7. Also I noticed water quality kills a lot of FPS even if there is no water in the view.

That's how DCS terrain engine has been working for years. The game fully renders a layer of water under the whole map and then puts land over it. So the water calculations always take place, whether you see it or not. One more reason not to be too optimistic with water quality setting even if you're using desert-mostly maps in your missions.

In questa missione predefinita F / A-18C con avvio a freddo, non ci sono nuove nuvole e nessuna superficie d'acqua, ma l'FPS della versione 2.7 è 10FPS inferiore a quello della 2.5.6.

Well I think it's clear proof that something is wrong ...

Yeah, I don't think 13 pages and over 315 posts is about nothing.

There's gotta' be something wrong. Even guys who have strong machines

with 30 series cards are complaining.

Indeed, the problem exists and it is undeniable.
We are on a beta version and it could also be understandable, we can only hope that the developers are already working to solve this problem. How can you buy other new modules if you find it difficult to run them on your pc?

Got to be honest getting a little irritated and disillusioned with DCS after years of investment. I want to love this game and I've spent a  fortune on a new PC, Reverb G2, Warthog, Modules etc. I tend to sit here at night boot up, run a mission, mess with the settings, change graphics drivers read forums  in the hope that something will give me a decent FPS. I then get P***** off and come to the conclusion just put it down till the next patch.  New patch...Repeat above!

 

Please fix the core game.

 

Apologies for rant, I normally keep my trap shut.

You know, it is like a water bed. You have to stop moving around so much on take off and landing, then that will calm down. 😆

Seriously though, since it is rendering under all land masses, if you (we) just set our water detail to low, then we should get a performance gain??

I know this has been beat to death. I am not getting a massive FPS loss, and I am not a 120 FPS system guy.

 

However, I know folks are having issues, and I was looking at some more NVIDA tweaks. I tried one more (along with others that contravene other advice!!!)

 

But, I want to focus on the one, that I think had the most impact. Max Frame Rate. In other games, I run 60 to 120 FPS no problem, in DCS currently (and in 2.5) doing good at 50 to 90 - currently 45 to 60 ish 2.7 Syria. So this tweak is to drop about 10 or 15 frames below what you normally average, and set your Max Frame Rate there. This does not affect other games like Borderlands 3 for whatever reason.

I did this mainly for DCS, and I can confirm using an FPS counter, it pretty much stays right at 47 - before it would float between 45 and 60+ on Syria. Higher on other maps.

 

However, no stutter, and rock solid performance. I hate it that another tweak I was using, kinda gets over written on other things with this tweak. But I would be interested in knowing if folks set this 10 to 15 frames below their best in DCS if it helps them or not.

 

If it does, I will go over the other tweaks I tried (that are somewhat different than other advice I have followed) and we can check those. I definitely got some smoother better performance with these settings - but I think MFR is the one that others can try and get a measurable verifiable benefit or not.

That's exactly what I had been doing. Spending all night tweaking the game. Literally tried everything ppl have been saying in the forum, including reinstalling DCS. 

 

In the end, I just gave up. Because lowering my graphic settings only gave me less than 10 fps increase, and it's still worse than 2.5.6. I didn't like my game looking bad so I reverted my settings to what I had in 2.5.6. Now, I just wait for ED can fix the issue and bring the performance back. Hopefully soon.

I second that. After buying it, I feel that I have been robbed since it’s not enjoyable anymore and I do not habe the money for a new PC. Game performance should get better with time and not worse! 30-40 fps loss on my side.

ranting - does not help
posting logs, tracks, bug reports etc. - does not help
begging the devs for improving the core engine - does not help

All you can do is buying the best hardware you can afford, tweaking it to get the best possible performance in DCS and hoping that it will be playable for at least half a year without major problems... which is more than unsure...
