Well, that’s very odd. I bought an acer laptop to try out Rouvy (and others) in the man cave. It worked, but died after 2 days. Tried it on the old corporate Dell laptop - no videos on Rouvy. Tried it on the current corporate HP, works fine. Tried it on another Dell (replacement for the Acer), no video. All win 10 machines. I’ve made sure I’ve selected the Rouvy app as giving high performance graphics (and thereby using the 4gb AMD card, not in-built Intel graphics) to no avail. Bigringvr, fulgaz, Zwift, sufferfest, they all work. Stumped.
