2080TI Performance - this can't be right?

Hi

 

After some advice

 

Just upgraded from a 1080TI to a 2080TI (other system in my sig)

 

Running

Vis range Med

Water High

Shadows High

AA x2

AF x8

 

PD @ 1.3

 

I did run the same settings with my 1080 except I had to have PD @ 1.2 but it was always smooth

 

Now with the 2080TI even at 1.3 I get an issue where the picture 'vibrates' when over a large city, down low, looking out to the side & down.... The issue is between a stutter and vibration of the picture

 

very frustrated as I was expecting for my £1200 to be able to easily run at PD 1.5

 

 

Did a clean install of driver

deleted the FXo and Shaders DIR

 

Am I expecting too much from the card and I should settle running at 1.2 PD :(

 

Any advice appreciated

 

Thank

Forget the Shadows at high, and the MSAA x2. As I’ve said a million times before, in VR, it’s only shadows, MSAA and SteamVR SS/PD that are important in terms of performance.

If your CPU is running closer to 4.9 GHz ( can't tell for sure from your sig) I don't think you should be seeing what you are seeing.

 

You said clean install of the drivers? Did you remove the old drivers with Display Driver Uninstaller while disconnected from the internet, and then do a clean install of latest drivers?

thanks for initial thoughts

 

I did not use Display Driver Uninstaller -- but did this morning - but the same issue remains

 

The CUP is running at 4.9 all the time via turbo boost - no heat problems

 

I could turn down shadows - but my point being I'm seeing no real improvements over my 1080TI (which I ran on high shadows) except I can now whit 80 FPS when not down low / over busy areas

 

I could not recommend the upgrade currently just for DCS

 

Good news is in diving sims I am seeing the improvement - so not a total waste of money

 

Any other suggestions on what he issue my be??

I would recommend the upgrade for DCS. I saw about 15-20% improvement with the 2080Ti compared to my old 1080Ti.

I am stunned. Why buy now a 2080ti? A card that is 2 years Old on full price? In 3 months the 3080ti is there with 40% increase to the 2080ti. Sorry, I simply just don't get it. Sure I saved the money too... just waiting for the real monster card. :D

Most don't seem to understand the OP's question. He's saying with everything being equal why he's not seeing the expected improvement. Not why he spent the money or "Works fine for me"

 

My guess is that your bottleneck is somewhere else. You have 16GB RAM. That's minimum spec for VR and 32GB is recommended spec.

I would agree. This isn’t his card isn’t fast enough- this is a stutter issue which often comes down to memory.

In addition to the memory issue already mentioned, the "vibration" when looking out to the side sounds like it could be that ASW on your Rift S is turned off. If it was running well with your 1080ti, try setting all of your graphics settings back to where they were with that and see if that gives you the same results you had with the 1080ti. But, as I said, the picture looking like its "vibrating" when looking to the sides and down sounds like ASW is turned off. Before you fly, try moving your head laterally and see if the cockpit image "smears". You can also turn on the in-game FPS counter and see if it is locked at 40 FPS. If the FPS counter constantly fluctuates with numbers anywhere between 40 and 80, ASW isn't turned on.

real question is, what resolution are you running in?

 

That's irrelevant. He said settings are same between 1080TI and 2080TI. Resolution is same in VR and he mentioned the PD he's running with both.

Can double check the SteamVR SS settings since if it's set to Auto, it might set itself higher with 2080TI.

looks like you ram clock is the bottle neck. one way to verify is to downclock your ram and you should see a significant lost in performance.

thanks all for the responses

 

I purchased 32BG RAM. got it running at 3.33GH (its 3.6 but will not boot at that rate)

 

Its better...... now can run

 

Water High

Vis range Med

Shadows High

AA x 2

AF x 8

PD 1.3

 

Without stutter (except the channel map which still stutters)

 

Can't go above 1.3 PD though else the stutters are back
