Big FPS drops with Rift S

[Mobius010]

Hello all,

 

I have a problem with my Rift S.

My FPS is a stable 40 or sometimes 80 when I am up in the air but mostly 40.

When I take off the Rift S from my head and put it back on after a few minutes or even a minute the FPS has dropped to 10 and is just unplayable.

I also get a big FPS drop (drop to 30 or even 20) when I look at the F10 or other camera's (this doesn't happen all the time).

I can even get a steady FPS drop to 20 or 30 when I am in a dogfight and move my head.

I can't play for a few hours straight without a big FPS drop.

 

Does anyone else have those kind of problem? Or know a fix.

 

Kind regards,

You know, these questions always require a little more information than only your Problem.

 

On such issues ALWAYS provide Information like:

 

- PC Specs (CPU, GPU, VRAM, RAM, PSU, cooling)

- How current are the drivers/Firmware.

- Are you experiencing the same issues in other Games

 

Only then People are at all able to help or give advice. To make sure that you never ever forget about your specs, put them in your Signature ;).

 

My first guess is that you´ve to low RAM or VRAM and this could cause the issue...but to say more I´d need to know your specs.

Agreed, need info on your pc specs and graphics options.

Also make sure you do not have vsync enabled.

Sorry for not giving you guys more info. I have updated my signature with my current setup.

My drivers and firmware are up to date of both Rift S and my GPU.

 

And no, I am only having these kind of issues with DCS

VSYNC is off

OP - see my sig/specs. I'm almost similar. DCS also likes higher CPU speeds. A 9700K begs to be OC. If you're running stock, you're at 3.6ghz. You can safely go to 4.9ghz (all cores), without an issue. With higher end coolers, some folks go to 5.0 and 5.1. (I'm not familiar with the KF version, so I'll look it up).

 

Also, please share your DCS settings too.

 

thx,

Thank you for your reply. I haven't OC my CPU because I don't really know how to do that. I will look into it.

 

My DCS settings are attached in this post.

AA setting: " "

AA Transparency: off

CUDA - GPUs : All

Low Latency Mode: Off

Max Frame Rate: Use global setting (off)

Monitor Technology: Fixed Refresh

MFAA: Off

OpenGL Rendering GPU: Geforce RTX 2080 Super

Power Management Mode: Prefer maximum performance

Shader Cache: Use global settings (on)

Texture Filtering - Anisotropic sample optimization : off

Texture Filtering - Negative LOD bias: Clamp

Texture Filtering - Quality: High performance

Texture Filtering - Trilinear optimization: on

Threaded optimization: on

Triple buffering: on

VSync: off

VR pre-rendered frames: 3

 

My Oculus Tray Tool settings are:

 

SS: 1.6

Default ASW mode: off

Adaptive GPU scaling: on

Oculus Homeless: Enabled

Mirror Oculus Home: Disabled

Just had the same issue again.. was flying with a steady 80 fps, looked on the F10 map and the FPS dropped to around 20....

[Bearskin]

Try it with PD under the VR in-game tab @ 1.5 and turn SS in tray tool back to 0, and pre rendered frames back to 1 in nvidia panel.

 

 

Infact turn nvidia panel back to defaults and just change to use maximum power.

reduce Clutter/Grass down to a minimum

get Chimney at least 1. 1 gives you a good glimpse of Wind directions without burning too much performance

reduce AA to 0, you don't need that in VR

Res. of Cockpits can be reduced to 512 for VR

Visible Range shouldn´t be on Ultra...play around with it

This happens to me alot!  it has nothing to do with settings.  I habe a 9700k at 4.9 and a 3090. Still does it. Its a rift thing i guess
