I have seen various questions about correct settings but nothing about Sierra. I am new to Wurm and have never successfully run it before - it will load but the graphics "stick" and there are semi- to multi-second lags between frames when moving around. Even getting the settings window to popup causes a delay. My basic info can be found here:

4GB Ram, 512MB VRAM
I have lowered many of the graphics settings (but maybe not enough?), I have a 25mbps internet connection and I can run other games (like elder scrolls online) with no problem. Apparently, I am using Java 8, 111.
Anyone have an idea what's going on? Thanks.
