You needlesly degrade LOMAC.
Ubisoft pulled the plug on ED so they were pushed into an early release.
1.1 is bound to be tons better. I will probably buy it.
LOMAC however is far from being as unstable or performance low as some put it. It was designed with high-grade top of the line PCs in mind - therefore you won't use the high detail on an average system.
I have a pretty outdated videocard that forces me to use the lowest possible detail, and LOMAC still benches most of the compentition IMHO.
There is a trick though:
First off, apply the patch. It solves the 99% of the buggyness.
Next - use Loman.
It is user made app to in-depth tailor the settings of the game. It is widely used by the community and it also makes adding usermade training, missions, campaigns as well as mods a breeze.
Last: grab the fast overcast mod and the optimized explosions mod.
Those two features went a bit over the top, but with them replaced / toned down even my obsolate system could handle the game flawlessly.
