It's reassuring to see what my current integrated graphics rat can run, so I ended-up putting about 45 minutes into Darkest Dungeon 2 this morning (also based on the narrator's voice actor dying, unfortunate that is) and it plays great. Not a solid 60FPS most of the time, but that's also unnecessary for the type of game; I tested a few others as well, including Deus Ex: Human Revolution, which actually runs pretty great on the integrated chip. Had had some issues with it previous, but they must have been heat related. Even got some Aliens: Dark Descent in on the integrated chip and that ran...playable. Low Settings, 1280x800 and started to dip into the teens as the computer got hot, but otherwise was fine.
So, I've just ordered the Honeywell Thermal pads to put on my laptop. The Kyronaut I had on here was great when I initially did it, but it's not doing its job anymore; I had no idea thermal paste would pump out so quickly, which explains the heat issue I have with my Steam Deck occasionally as well, so I think I'll go ahead and see if I can apply the stuff all around, maybe even my GPU. I'm hoping to eke out just that little bit more performance out of this machine.
I also went and found myself another PC power cable to keep plugged in at a different spot I like to use my laptop. Makes moving my eGPU that much easier not having to get under the couch and try to unplug it and then replug it when I'm ready to go back, so I can be more mobile in the house again. Not sure why I didn't think of that before...
Anyway, thanks for talking to me about it, all. Helped alleviate that FOMO for the time being and stop me from spending a ridiculous amount of money on something I don't need and selling a computer I actually really like.
