I can confirm the Lyra2rev2 issue is entirely ccminer related and nothing to do with the pool.  If you try https://github.com/Nanashi-Meiyo-Meijin/ccminer/releases/tag/v2.2-mod-r2 which is a fork with improved lyra2RE2, hashrates are greatly improved and what's displayed on site is pretty much the same as locally.  You might need to be sure your nvidia software is totally up to date (388.59)
