I use the kentie's launcher. I did not use the DX9/10 addon or any texture packs.

My Settings worked great for me: -OPENGL (tested all of the renders, D3D had some input lag, software rendering had rendering bugs), opengl works great although the lighting isn't as good. If you want to mess around with libaries, DX10 would probably work the best -165fps cap to match my monitor refresh rate, worked great -Resolution: 1280x960 just because the old school looks feels more natural but works great at 1920x1080 -Use Directsound with 0 latency -FOV: Automatic -32 Bit colour with detailed textures -Raw input -If using I3 disable your compositor

Runs good out of the box esp with opengl selected - with some tweaks it runs better than windows
