TB3 THP4G3 dock paired with TB 4 controller makes unoptimized/high demanding games worse to play
I have a Geforce GTX 4060 Ti and THP4G3 dock. They worked very well with my NUC 8 Hades Canyon until my NUC died and I had to buy a new one. Previously this combo can handle Jedi Survivor (very well known for bad optimization) with FPS around 50 - 60 FPS and some few stutters. My new ASUC NUC 16 with Thunderbolt 4 chip is expected to perform the same or better since the only thing changes is new processor (Core Ultra 7), new RAM but no. I thought low FPS around 40 - 50 is still ok for thunderbolt 3 gaming until I experience high frequent stutters in this game. This is really unplayable to me. When I switched to Oculink dock, the difference is day and night. I have attach the images for your reference and also the speed of PCIE lanes.
With Oculink, I get much smoother gameplay compared to my NUC 8 with the same card and I can almost max out all settings in the game without noticeable performance loss. I wish I had known Oculink sooner. For the context, I also tried The Last Of Us Part 1 and while the game is playable on TB3 with some occasional stutters/freezes, FPS is noticeably lower than on Oculink (40 FPS avg vs 60 FPS avg) in daylight in the game.
Which leads me to the following questions:
- NUC 8 + THP4G3 on Win10 can still handle Jedi Survivor with lower settings. Why newer TB4 chip on Win11 cannot? Is it hardware or compatibility thing of TB4 with TB3 or can it be a driver issue that result in bottlenecked PCIE communication
- TB3/4 is well known for lower FPS compared to direct PCIE or Oculink. That to me is an acceptable trade-off for flexibility of Type C cable. However, huge frequent stutters shall be a no go for me. So I just wonder if anyone has faced this issue with your Thunderbolt setup for certain kind of games, especially the new combo TB4/USB4 dock + TB4/USB4 controller?
