1080ti is not enough for 2.1?

Hi, I use Oculus with a 4770k, 32gb, ssd and 1080ti.

In 2.1 with Spitfire I use vr preset settings.

My fps dance between 17 and 32…

Can I do something to improve the performance?

drop the shadows, instant performance boost. And don't go over PD 1.5

you can also overclock your CPU and GPU if you havn't done so already, those numbers seem too low for me. I got higher framerate on 2600K w/1080.

Also..Check this thread.

Defered shading combined with msaa eats fps too.

The spit is the most frameratekiller plane on dcs.

This great vid from Jabbers can help you out.

Ok, Spitfire is the problem.

Other planes run smoothly with 1.5 supersampling (70-90 fps).

Spitfire is between 15 and 30 without supersampling and lowering settings as described in the previous video.

I'll put the Spitfire in a locker waiting a miraculous patch.

Defered shading a killer for me. I have 1080ti sc evga.

Crashes in multiplayer, ok on single player

I won’t be buying the Spit anytime soon.

Have a look at this

You can compare my specs to yours but I play strictly 2.1, have a 1080Ti and never really have performance issues, especially in single player. Multiplayer just depends on the mission.

Update: the problem occurs only flying Spitfire in Normandy. In Nevada I can fly the Spitfire with fps between 70 and 100.

do you play multiplayer often?

thank you so much for making the video.

but i have to ask, do you run the oculus service only? or do you also run steamVR?

I only ever play MP, I only ever run Oculus, but I disable the Oculus home.

Ok, I found a strange thing that boost my fps from range 17-23 to 40-50 (Spitfire).

I have 3 Arduino in 3 custom controllers so in Input folder I usually have these files:

- x55 throttle + GUID

- x55 stick + GUID

- arduino 1 + GUID

- arduino 2 + GUID

- arduino 3 + GUID

In Spitfire input folder I found 2 "arduino 2 + GUID" files with different GUID and different timestamp.

Deleting the older one solved (partially) my lacks of performance.

Lowering a bit my settings now I can play the campaign with ASW enabled and solid 45 fps.

Of course we need a performance patch but I can wait it flying this plane.

deleting the SceneVR.lua helped me out alot!!!

with 16GB system memory, turn off the page file is also helping my dcs experience on multiplayer...

finally i can enjoy this sim!

Hi

can you please advise what the scenevr.lua file does? Is it a case of just deleting and it rewrites?

Thanks

Neal

The sceneVR lua file creates the view of the SU-27 that you see when you start up DCS in VR. If you delete sceneVR from your Scripts/Demoscenes, I assume you'd just see the splash screen with your menu. The SceneVR file will be regenerated by DCS during an update.

What is your system and how was the "boost" of turning off the page file ?

i have a 8700K (8th gen) with a evga SC 1080ti.

16GB memory.

not necessarily a boost...

more like, no crashing to desktop lol

i try to do most of the settings on jabbers video.

i felt like i have a comparable system, yet, i am crashing when i follow most of his settings.

as share by others, high textures, MSAA, deferred shading are killers.

Using Jabbers setting, just have HDR on and DS off. Flying fine.

If you turn of the pagefile and run of out of memory DCS will crash...

you are right.. so ppl that have alot of system memory should have this option....

but if u dont have alot of system memory, u keep the page file..

DCS should by default use System memory. the "when to sent to swap" call is on the OS.

However disabling swap on windows is a bad advice. I would recommend tweaking it if needed (say reduce total amount of pagefile available, or moving the pagefile to a drive not containing the OS or DCS).

In Linux there is a system setting called "swappiness" it controls when the kernel will start using swap. by default it's set to 60% free RAM (i.e it starts using RAM before half your memory is used). on high performance applications that are very sensitive to memory you set swappiness to 1 or 0. which means that swap will be used only when RAM is 99% or 100% full. But you never ever disable swap completly..

Windows unfortunately has no "swappiness" setting as far as I'm aware.
