Works fine here.. Just slightly slower than native.
Specs:
Gentoo 1.4rc2 (sync'd t o current)
emerge of (masked) winex-cvs (WineX 2.2.1)
Kernel 2.4.20
NVidia latest kernel and GLX drivers.
Btw, I run it under KDE 3.1. Run it in non-windowed mode (eqclient.ini setting), uncomment "Desktop" in your wine config file and set it to your eq resolution, and (if you want your mouse) set DXGrab to "N". Bingo, EQ in a windoe under linux.
To switch out.. Alt-tab and hold it, then move your mouse out of the EQ window then let go of alt-tab. Works great.
Btw, if you are not using Gentoo (
www.gentoo.org) I would suggest switching. It has a ports collection like Open/NetBSD. It's wonderful.
