Testing TB Throughput

Greetings!
I'm having some lag and frame-rate issues with my setup. In Ghost Recon Wildlands, there is so much landscape and detail visible all the time, the game is constantly loading textures and models. When there is a particularly rapid change, such as whipping across the landscape in a helicopter, but other time when just running around, and especially when auto-saving at the same time, the game will hang for a solid three to five seconds. Also textures seem to load with a serious delay, seconds or so after I've arrived in a location, sometimes to some very frustrating effects (like mission vehicles aren't there for a few seconds, or I'll be driving on a road with only the long-distance blurry texture on it). If it hangs when I'm in a vehicle, I can still rotate the camera around but the world is effectively frozen. Then it unfreezes, loads properly, and life goes on! But it's every few minutes and it's bugging me like crazy now.

I've replaced my SSD drive, enclosures, reduced resolution and texture settings, all to no avail. My next step is probably to start fiddling with various NVIDIA driver releases, but that feels like a gamble. I was hoping someone could help me better troubleshoot this; I'm thinking this may just be a limitation of the throughput via the TB3 >TB2 adapter I'm using. Is there any way to check where the bottleneck is (in Windows 10)?

Thanks in advance for your  awesomeness.

What resolution did you set in your game's settings? I also have an external GPU via TB3-TB2. Any resolution above FULL HD (1920 x 1080) gives me low fps/freeze etc on Internal Screen.

I was able to use a 2K resolution on a TB3 Aorus. Works well on either 16k or 22k H2D connection.

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

I have a 1070 and a 13in ch 2017 MBP and haven't experienced this in Wildlands, I'll try and give it a good play over the next week or so and report back. 

I wonder if it's your CPU thats the issue? This game is super CPU intensive (I believe) and plays the worst out of all the games I have tested (check in my sig).

I believe this is the answer. Regardless of theoretical bandwidth availability, once you get above 1080p/1152p, your ability to run at 60fps is virtually impossible on at TB2 connection and internal screen. I think I'm going to publish my tests with the new Spring Creators Update and TB2 internal screen. But basically, even running something as simple as Google Chrome, 1440p is going to max out at around 45 fps. 4k will max out at around 30 fps. 4k+ and you are looking at 24 fps.

When you run a serious game or application, those number get knocked down even further. Again, if you aren't using Nvidia Optimus, give the Spring Creator's update a try. It performs much better than using the ghost adapter dual display option.

Thanks everyone for your thoughts and ideas.

I can play GRW as high as 4k, with most "very high" settings, but I think the frame rate is around 30fps! If I include the advanced turf setting, or ultra settings, usually the game will crash sometime thereafter; I think that is a RAM issue (not VRAM). But the intermittent hanging and texturing loading lag occurs at all resolutions and graphic settings that I've tried, and it just may be the game itself; I saw there was an update I don't have which came out to fix graphic lag among other things, but NVIDIA support was supposed to be excellent from before the update.

My original question, sorry I like to bury things in verbose descriptions (case in point), was how to measure TB throughput? Maybe that's irrelevant? It just seemed like something people would want to do if they were troubleshooting eGPU performance.

Hey @bootz! Sorry, I was composing my reply to the previous when you posted. I only play on my external display, but I concur that the frame rate is pretty limited at 2k+ on TB2. Do you think this would improve significantly with TB3? I'm getting a Macbook with TB3, so I guess I'll find out. Looking forward to updating my firmware as well.

@comfycat,

I believe what you are looking for is CUDA-Z. That will show you your stats, and you can compare to other members and/or applications.

Thanks @bootz, I'll check out CUDA-Z.

Sorry for bringing this thread back. I have the same scenario on AORUS except that I'm on AMD/Metal. What tool can I use for Windows? Thanks!
Ive read other threads about MAC and AMD but my OSX is not compatible out of the box and I don't use it.
I don't get that problem but I do run at 30 fps on internal. Check my signature for details. I'm on 1803 Windows.
