nvidia control panel -> Global Settings -> Shader Cache size

 

i don't see this setting, maybye i have to old GPU, only setting similar i se is shader cache on/off, can You add a screenshot? Thanks!

[speed-of-heat]

sure

Thank You, i don't have this setting available, perhaps i have older GPU GTX 1080

[Dunx]

I can confirm that the 1080 Ti includes the Shader Cashe Size option (game ready driver 469.49)...

Older driver perhaps. i have it on the latest ones

Yeah, 442.19 but DCS performs best for me on this one.

Let me know if it makes a difference for you. thanks

alas functionally no difference maybe .10 ms GPU frame time, but that is so close to noise as to be dangers assumptions wise... right now i need to prep for my new CPU and MB to arrive ...

Id stick to it. A quick look ariound the net doesnt bring anything especially encouraging. From what I can glean 256Mb is the driver default, reducing it may have limited benefits for faster cpus and increasing may have limited benefits for slower cpus....in theory....dependent upon the drives.....and if its a tuesday ....etc. . It goes back to the enable/disable cache debate I think which proved a rather pointless rabbit hole for me. It seems to be more about load time stutter too. Not overall fps.

Either way, the more I really look at NPC the more I feel leaving the majority of it alone works best. For me Disable Gamma correction for less AA on fences, Prefer max power, Allow LOD bias, Texure filtering AA optimisation off, Texture filter quality Performance, Texure filtering optimisation On ,everything else to set to use application setting.

Any of the setting are "niths" of an improvment, if at all.  The loss we an collectivley experienceing is well over that.

This is  no crtisism to anyone setting it however. I just think its very system dependent and more of a fine polish than a grindstone. .

Ed should fix that issue, the problem is definite, game is not same as before.  Why are we still trying to prove something?  Our hardwares and game settings are same, only one thing has changed "the 2.7.7 update".  This is the evidence.

The existence of a probelm for some has been demonstrated and reproduced by a DCS ground crew member. ED states however that the problem cannot be pinpointed. This irregularity in gaining and loosing fp has also been expereince by those of us who have continued to tried different things which supports EDs position. So whilst there is evidence, there is no solution at this time, hence some of us are continuing (perhaps pointlessly) to find a smoking gun.  

You are right ED should fix this. Im hopefully they will if they can get to the bottom of it but im equally doubtful it will fully return to the 2.7.6 performance.

Again - its was meant in jest as a title to sum up the the loss we are all at as to the reason behindthe loss and the random nature of it.

[Hiob]

We're not trying to prove anything to ED. The problem has been acknowledged already.

Everyone engaged in this topic here is just trying to voluntarily help in finding the root of the problem, or at least reveal some clues on where to search for the fix.

There are basically two choices:

1. Wait for things to improve and be passive (apart from complaining)

2. Try to engage in the matter and help to find the problem....

It's on you, how to deal with it.

another thing to keep in mind. Windows is also in the mix and with that said there could very well be something besides DCS causing issues. there are are quite likely many (perhaps hundreds / thousands) people that do not have any discernible problems day after day.

[Esac_mirmidon]

Like me. Same perfomance before and after.

[Raven434th]

hey WHY can they not just roll back to 276 graphics and add the aircraft fixes in and say "yeah we know there's an issue with 277 but we can't figure it out so here's an interm fix" doesn't seem to me as an unreasonable solution.

AND I'd like to know if this isn't something WE can do ourselves??

Not sure if you have covered this elsewhere - apologies if you have. Do you find that DSR improves things? I notice this is only a global setting....

Fortunately ED don't work that way, otherwse we'll still be flying this good old DCS 1.5.

The issue is now reported. Wait a bit and see.

You cannot, unless you find DCS source code and you master C++.

[SMH]

Same. Used to see about 45 FPS when looking straight up at empty sky. Now get less than 30. (Suspect it's poorly optimized textures. My GPU only has 4 GB VRAM. Everything was fine before the October updates though.)

This is in all maps but Marianas is even worse.

i believe everyone has it and those who don't see the issue are just bruteforcing through 

seeing reports of no perfomance loss in 2d but necessity to lower the pixel density on vr to regain performance on the same system should point to a gpu bottleneck

There is loss in 2D if you meant specifically 2D players. But its us lower spec vsync dependant potato pushers who seem to be suffering most obviously. Again those with bigger specs may be oblivious to any marginal loss that fails to impact on their specific settings.

This, 100%. I see no issue in 2d at very high settings, but have to reduce PD in VR and still have a significant loss vs 2.7.6. The refrain of “it’s probably lower end/older systems” is frustrating, as I have a fairly top-end machine. Hoping they get it sorted soon, but really, overall, the sim needs optimized badly. This wouldn’t even be a conversation if good performance in VR were a thing in DCS (in liberation or any sort of complex mission, decent frame rates on decent graphics settings look like ~40fps w/ my machine pre-2.7.7).

this is because if you are running a strong gpu, say a 2080 or the newer 30xx series

most of the time you are VERY cpu limited with gpu headroom to spare, so any increase of gpu render time,up to a certain point, is basically invisible in your performance profile

there is no vodoo magic here

 

 

 

in my case it is immediately visible because my system (ryzen 3600 rx480) is gpu bound 90% of the time

Yes it would. The thread was started by a non VR player, has many posts reporting loss from non VR players and the issue affects non VR players. Maybe take of your headset long enough to read through it before posting such garbage.

Sorry, plain wrong. 

I have a 3080 and am GPU limited 100% of the time. The only difference is, I can probably ramp up the visual fidelity much more.

[MattCri]

not plain wrong, id say partially

you should consider that a gpu is not a monolithic thing, you can bottleneck a single part  (say memory bandwidth with 4k and msaa) and have room to spare in other blocks (like compute and shaders)
