I use it on my XP retro build with a CRT monitor and honestly is all I need, I'm not missing anything. I hope this doesn't fall in oblivion.
Edit:
While archive.org is down, I discovered the links to the builds are missing on the original website, but the files are still hosted there. You can browse them using the wayback machine, that seems to be working again:
https://web.archive.org/web/20211011175017/ht … .net/dosboxece/
Sadly the build files are not archived, but you can use the wayback machine URL to deduce the original download URLs. Like this:
https://yesterplay.net/dosboxece/download/arc … 0ECE%20r4301.7z
https://yesterplay.net/dosboxece/downlo ... (Linux).7z
For instance this is the last version that had the pixel perfect plugin, I'm interested in the opengl vsync feature, and it works like a charm. Other releases can be downloaded just modifying the URL to the right build number.
