Just tried AC in VR

Yes that is very worrying considering my vega rarely crosses the 50% usage in AC. The drivers must be causing some massive overhead on the cpu-draw-calls.
Its almost as if Kunos did the entire development without a single AMD card in the office and did not even request input from amd (they respond and send engineers if needed). This isn't just some indy game.

anyways it seems i'm screwed.

 

Sell the Vega 64, buy Nvidia, problem solved

 

I have some issues giving nvidia money lol.
It doesn't make a dent in their financials but I feel sick to my stomach just considering the idea.

 

Does anyone have any idea why my oculus screen mirror on my monitor is solid red, no image?

I thought it might be because I was running oculus as admin but it's not that, can't think I changed anything else and have reinstalled oculus software.

Thanks

 

did you change the oculus.ini in C:Users/"Your username"/Documents/Assetto Corsa/cfg ?
guess you / it set it to 0, so you don't see the game when the track is loaded on your monitor

[MIRROR_TEXTURE]
ENABLED=1

Questions I have to all who read here are:
Does it saves fps in VR when the mirroring is off ?
and is that red changeable with a another picture or is it hard coded?

 

Ah, that's it, thank you Jack - don't recall changing it but that did the trick

 

Great!

Did you see the other options?
seeing your specs you could up the pixel per display if its still set to 1.0
(if not using that tool to set the PPD I forgot its name lol) OculusTrayTool !

will give a sharper picture but costs fps, its a bit experimenting

[SETTINGS]
AUTOSELECT_RIFT_AUDIO_DEVICE=1
PIXEL_PER_DISPLAY=1.4

oh looking in your sig I see you have already a PPD of 1.8

 

Yet you have no issues with giving FB money

 

why is that, if I may ask?

 

I have a AMD card and it works great with AC.

 

I have been playing around with the setting via Content manager , if you hit the (i) button beside each option it shows how much of an impact to the system the different quality settings have.

ie. So shadows at low are 1% performance but at High 5% , but meduim is only 1.7% so you can more effectively set the level to give a good balance between looks and performance.
(these values arent exact to what is shown in CM just a rough estimate to what i was looking at last night)

I've now got my PC (specs below) running mostly at 90FPS when 1 or 2 cars are in view but drops to 45FPS when the full pack is in view.
But its not really noticable when the switch between the frame rates happen.
(I'm running a few mods too , GBW suite 2.2 (with no reshade) , PP low - Brakelight only ini file , Real Billboard , Crew chief , RSR)

 

Load temperatures? I had better performance than you with a 4690k and 970

 

YOu are right that the CPU is mostly the bottleneck but in your case it should not be a big issue.
Have you tried without VR? Your CPU @18% should not bottleneck unless AC is bad at Multithreading.

Are those tracks originals? Because user made tracks can be horrible in performance for VR if made wrong.

I ran an AMD Phenom X6 which's PassMark is 5500 vs 17k of yours and a GTX 970 and could drive a match against 8 AI opponents without lags.
I could run the game at 1.6 resolution, 2xAA and mirrors on low @45FPS.
Do you have downscaling on e.g. in ACs Oculus.ini or SteamVR, which renders in higher resolution?
Otherwise I can't help, it should run significantly better than on my machine. I only experienced issues online from time to time, maybe it is networking issues?

Why is that?

 

whats that? facebook?

AC uses two threads.

Here is an example from a few weaks ago, in windows 10 ver. 1709

Praga Online race @ Brands Hatch 24 cars -> all settings medium, PP very low, mirrors OFF.
The Framerate went down ALOT and when it happened the CPU would not go above 18% and my GPU was bored out of its mind at a measly 30% usage.

I just cant support that company and love pc gaming both at the same time. Choosing the first is killing the later.

 

Here it is

2 Laps @ mugello + Porsche GT3 cup. 20 something cars in the server. Every setting OFF or lowest.

(if youtube doesn't show 144op 60fps, its because its still processing the video)


I dont have to say anything more.

Tomorrow I will try Windows 1709.

 

Well, that is indeed strange. Your system should easily run AC with higher settings.

First of all, sorry I have to ask, why the odd resolution in AC?


Secondly, check the Steam VR SS settings. I've heard that in some instances after recent SteamVR update it applied SS settings automatically (it actually might be your case). So when you apply PPD settings in OTT it multiplies this with SteamVR SS settings (hence the FPS drops). Also, check the .ini file in AC, to see if the SS is not applied there.

Thirdly, try with ASW off. I see in that vid that you have PPD at 0 and ASW - auto. ASW tends to lower the FPS to 45 even with the slightest drop from 90. Try CTRL+1 when you are in pits.

 

The odd resolution could be any other low resolution. The trick is to keep that resolution low. I found about a year ago that this vr mirror (and gui) resolution affects the in-game performance massively. Try it.


From the image quality you can see in the vr mirror screen, its all running @ VRSS 1.0. Extremely jaggy and aliased.

ASW AUTO or FORCED 45fps produces the same amount of stutter. The difference is that in Auto when the game "thinks" its running @ 90fps and unlocks ASW, it actually stays around 88fps and it stutters massively.

This is all stock. Fresh windows 10 install + fresh AMD drivers + fresh Oculus. All up to date. That is the experience you get.

 

The experience you get.

Hope you get it solved, hardware issues are the worst when you just want to fire it up and race

 

I didn't meant it any other way.

 

@Daniel ... you can turn off the VR mirror to the monitor via the ini files...

Documents/Assetto Corsa/cfg/oculus.ini
[MIRROR_TEXTURE]
ENABLED=0

The resolution that is set in the settings menu should only affect the apps overlay in VR.
