New machine and steam VR settings

Just wanted to share my experience after I started using my new machine.

I was initially disappointed the VR performance had not increased, I was getting the same performance as my 4790k ( which wasnt bad ).

I was having a play around with the settings, in particular steamVR. The resolution was set to auto, and the each eye resolution was much higher than the reported resolution of my Vive cosmos at 100%

Decided to set it to the reported resolution manually which was about 50% of what steam had set, obviously the clarity dropped but I was getting 90 fps.

Decided to play around eventually setting it to 90% and getting a steady 45fps on the ground and 60+ in the air.

It may help some who are having problems with fps to try and find a balance between the steam VR resolution and your desired frame rate.

Thanks

I keep my settings pretty low, I don't mind jaggys so much, I prefer higher frames over anything else.

Wow, that is pretty low

 

No Shadows

No MSAA

No Anisotropic Filtering

 

Interesting you leave SSLR on

 

 

Do you use fpsVR?

 

if so, what are your:

GPU avg frametimes?

CPU avg frametimes?

 

Thank you,

Monnie

Well spotted, I did not intend to leave SSLR on, will install fpsVR and check it out later

edit with SSLR off another huge increase for me, dont know how I missed that. lol

Congratulations on the new system. Wife debt increased 200% :lol:

 

 

Thank you,

Yeah dont worry, already paying the emotional price for this purchase lol :)

BIGNEWY are you on stable or beta, for the first time I have gone back to stable as beta lighting I dis like.

I use all as I have to test, but mostly open beta. Many like the lighting, but I am sure personal preference will play a part if you dislike it.

With SSLR off I will be increasing my ingame settings, will play about with it later to get it where I want it.

you force IPD to 10? I'm confused ?

It makes the scale of the cockpit look better for me and helps with some cross eye I was getting when looking at the HUD and the HUD frame.

@Bignewy, that is a rather high-end system you have got there. I would advise with SSLR turned off, you could turn on some level of antiliasing and other eye candy on. Some good allowance.

I like sharp visuals aleast with a playable framerate.

 

Edit : I noticed your Pupilary distance in dcs vr setting is on 10, doesn't that make the cockpit rather huge and the pilot very small.

I dont use the pilot and would rather the cockpit felt the same size as me in real life, and as the name would suggest I am a big chap.

also I find it easier on the eyes and solves a cross eye problem I was getting

Now put steam vr settings to 150% with SSLR off, anistropic filtering x8 still getting good frames.

Hi BN....congrats on your new build....did you change everything but the video card correct?

 

Anyway....how do you feel without using shadows at all?

I mean, the cockpit with shadows off or flat is really strange and not so pretty...it has a big hit, so a cockpit only shadow option would be interesting

GPU and some hard drives from the old machine, but the rest new :)

I have got used to flying without shadows in VR, but I may try cockpit shadows now, will report back later once I have given it a go.

thanks

With shadows low Im getting good frames still, except when on a busy super carrier, with shadows off even on the busy super carrier I am getting 45 FPS+

Pretty happy now with this, worth the investment after all :)

You really have to take the headset into account. On a Rift I would never play without shadows, but on a Reverb I do not miss them at all.

Yeah I think you may be right here, with the cosmos it never bothered me, I used to have a dell visor and it was much lower resolution.
