Hmmm... what are your system specs?
Are you running master update?
Have you used the multi-core fix?
Any other optomizers/running?
Have you done a cell reset since upgrading?
Increased instability ONLY after 6.01? Was it okay with 6.0?
P.S. . . . I hate the gamebryo engine. Beth, when will you adopt something more stable? It's 2010!
Dual Core 7500 processor from Intel, forget the exact specification. GeForce 9800GTS Mobile (laptop)
There was a masterupdate done, no multi-core fix because it actually makes my system less stable for some reason. GBoost for turning off background processes.
Cell Reset with eight day wait done for the 6.0 update, but not the 6.01 hotfix.
It was fine on the trip from Ranger HQ to Megaton last night (after 6.0 and cell reset), but very unstable today (after 6.01 without cell reset).
I removed the Workbench Items Rebalanced mod, which resulted in a new merge.esp and masterupdate done again and it was more stable after that.
Two things though: I'm in RobCo and Protectrons are wimpy to an unbelievable degree. A couple of shots from an Assault Rifle takes them out before they can even aim. No threat at all.
Stealth Field should probably default to on when first activated.
