It's a problem with the physics engine of the game. I avoid ladders going down and jump. I'd rather take the damage than get stuck.
I've gone through 3 revisions of the nvidia drivers and have had it happen on each.
It may not affect ati owners, or it may only be an sli thing.
My rig is as follows
Intel q6600
8gb ballistix ddr2
primary geforce 250 gs
physx geforce 8600 gs
On a full playthrough it usually will happen once or twice, I try to descend a ladder and the game just has me climbing down without moving. The character animation is going, but I'm not moving.
It has only ever happened to me in combat situations, and I fall when I get shot, but it is annoying to no end waiting for that to happen.
Hence, I just jump whenever I can.
Sorry I don't have a fix, but more info is always needed on the support side.
You should probably list the following specs
CPU:
ram:
motherboard:
primary video:
physx video:
sound card:
operating system:
chipset driver version number:
primary vid card driver driver:
secondary vid card driver number:
sound card driver number:
If you are running a retail built rig (HP, Dell, Acer) ignore the motherboard spec request, just post the full model number.
If you are running a custom job, chipset revision would also be helpful.
