With these it's better but still a bad. There are still pauses but they are a bit shorter, the start time without intervention is still around 2min. Start time on a good is around 1 min (assuming first run or mem caches flushed). Hud wise - pic to follow the vram req/used match well, but the gtt is still different from a good. On the upside - Unigine Valley is the best I've ever seen it - way better than what I've called as good in the past.
