EGPU Stuttering and FPS issue

Hello all,

I have recently bought a sonnet breakaway 350W for my Dell XPS 9560 and  I have put in a Zotac 1070ti mini.

I am running  a 24 inch external asus monitor. The laptop is connected to the breakaway by the included thunderbolt cable, and then a hdmi into the monitor from the back of the breakaway box. I have installed the newest version of Thunderbolt 17.4.77.400 and the most recent NVIDIA drivers through the experience software. 

The problem I am experiencing is low FPS and stuttering. I have tested the setup with Assassins creed Odyssey and it runs, just at 35FPS average on very high settings. Lowering the settings to high or medium does not make much diffence, which is a bit strange, 

The big issue is the lag spikes, and stuttering. Which is also present when watching video on VLC or the BBC iplayer app. Which is not right.

I have tested the monitor straight out of my laptop and there is no issue. I have tried to disable manually through device manager the intel inbuilt chip, and laptop 1050 but this makes no difference.

I would really appreciate some new ideas as I am sort of out. 

Thank you in advance.

Hello Ben

My egpu has a simelair issue. I'm using a dell xps 15 7590 with a razer core x chroma and a rtx 2080 super. Have you found a fix for the problem?

I have good fps in games but everey couple of seconds i get a stutter even when i'm not gaming and just browsing the internet. Even when i am at my desktop and open a file explorer window start moving it around i notice it is stuttering a bit any tips? 

als the image on my screen doesnt seem super sharp its a bit blurry in my opinion (i am using a z35p connectet via displayport)

Did you ever find a solution for the stuttering problem? I have the exact same thing with my Precision 5540 and a razer core x.. everything seems to be lagging a bit behind / hang for a few ms every second or two?

Hi,

I know I am a bit late but I was experiencing the same problem. I recently bought a Razer Core X & I installed a 3060 Ti 5 days ago. I was expecting to play 100% fluid to all my games. However, I clearly noticed a problem while playing Outer Wilds: the first loading screen where the camera goes down from the sky to the campfire, I had like two or three "image jump"; it was definetely something weird on the screen. If I had to describe it, I would say the screen "lost" a couple of frames.

I Googled this problem and I resolved it by disabling my old 1050 GTX (intern) + the Intel (intern). Only remaining GPU was the external 3060 Ti. I tried my game again and it was finally fixed!

I also tried to enable the Intel one again and the problem didn't come up. I assume it was the 1050 which was causing a conflict.

 

Hope it may help somebody having the same kind of problem!

Hey! 

Anyone having this issue; simply use the HDMI port on the laptop, not the eGPU.

Electricity moves fast, but they have rewired the multiplexer on these to that HDMI port on the laptop from the TB3 port.. 

While theoretically you could get faster speeds were this not the case, I manage to get a good 50fps using my 980TI on cyberpunk with high settings and this setup.

Also, don't forget you can squeeze more from the card with an overclock.

Hope this helps! 

Oh, and fyi, resulting from this, your internal monitor will perform equally as the external.

It's a trade off, but gives better performance overall and convenience for those who don't wish to use an external monitor.

Additionally, if you know your stuff, you can likely override this so the data flow is simply CPU > TB3 > eGPU > GPU Outputs (as opposed to CPU > TB3 > eGPU > TB3 > Multiplexer > Display/HDMI
