As the title says. I severely dislike having to make accounts for every game publisher that wants to send me advertisements, collect data or whatever.
It's usually an instant dealbreaker for me at this point
Publishers needing their own launcher already puts them on shaky grounds with me.
But I really liked the original BG 1 & 2, so I'm willing to not just refund it immediately and actually ask around first for solutions.
Triple buffering basically means that the GPU can temporarily store frames in three different locations in VRAM. This has implications for smoothness and frame time, so it should in theory always be the best option for v-sync and avoiding tearing.
Vulcan should be more efficient so you should get somewhat better performance, though my understanding is it depends on card (AMD cards are kind of designed for Vulkan, but not so much nvidia cards).
