Review: Was working when I first installed it. I'm using it with a GPD Pocket 3. Make sure to download the Nvidia drivers direct from their site. The Windows Update Nvidia drivers make it look like it's all good, but it doesn't actually work. I have a RTX 3070 Ti installed and it'd lag/stutter trying to just play 4k video. Once I installed the Nvidia drivers I downloaded directly from their site, it started working fine. I'm using a wifi biscuit, so I can't test out gaming yet. I don't have enough bandwidth left to download a game to test. The first problem I've go now, the USB ports don't work. They were working fine, but as soon as I installed Synapse 4, the USB ports no longer function on it. Doesn't even show up under device manager. I have it set to show hidden devices, nothing. Just not there. It doesn't show up under Synapse either, so can't configure it. Edit: Now the device likes to randomly disconnect, then reconnect. Other times, it'll just fully disconnect and I have to pull the Thunderbolt cable and reconnect, hoping it actually reconnects. Sometimes have to just reboot. I'm hoping this is more an issue with GPD Pocket 3. Will see how it works with a MSI Claw 8 AI Polar, when I get it in July.
