Thanks for the trainer. Inf. AP works great now with only a slight lag, but that's perhaps on my end or problem in the game, no crashing that's what important
Tried the Max attributes and weight 999, unfortunately it changed con to 999 (only in character window, didn't show any difference bellow the avatar on the main screen) and boosted some skills, but it didn't change the weight limit, which was a shame.
For some reason I had no problem with weapon range (but to be fair I only used inf. ammo and inf. AP options, hope it helps in identifying the problem others seem to have)
