I'm thinking specifically of older titles, I just tried this will things like Test Drive Unlimited and COD World at War. I go from the card underclocking itself, and having 50% usage at 120FPS. Enable 3D, clocks and usage get lower, frame rate dies, dropping the resolution and ingame settings do nothing?
Why is this? I get some games aren't exactly designed with 3D in mind, but I don't get how rendering the scene twice makes the GPU lazier.
Thanks.

Have you tried setting the specific games you are playing to "Power management mode: Prefer Maximum Performance" in the nvidia control panel?
I find this will help with any downclocking/slowdown issues that aren't related to bottlenecking.
what 3D mode are you using in the tames?
for example crysis 2 is side by side 1920x1080p, but crysis 1 and Far cry 3 are 3840x1080p for me. this is because i use CheckerBoard for the later two games meaning the video card has to send 2x 1920x1080p images to the TV. it's also the reason i purchased a second GTX680..

Checkerboard is an interlaced format, each frame is 1980x540. every odd pixel in one frame, every even pixel in the other.

Thanks for the responses. I have tried disabling the power management in the past and it didn't really effect FPS at all, it just dropped the usage.
I'm not sure what you mean by the format. I'm using 1x Asus VG278 if thats of any use.
From what I've heard the other half of each frame is discarded, or maybe it's simply seperated into each half. I never looked into that part.
But being that checkerboard is an interlaced format, it can only show half of a frame at a time. Even pixels in one, odd pixels in the other.
Just like line interlaced can only show half a frame at a time. But with line interlaced, it is every other row to eack eye.
reason i say that is that checkerboard games run at half the speed of 2D at the same rez. SBS 3D run at the same speed as 2D.
it would make sense not to send the full image given the odd even pixels but surely that would render at the same speed then?
try reinstalling the driver (select custom install and then clear install)
NVIDIA TITAN X (Pascal), Intel Core i7-6900K, Win 10 Pro,
ASUS ROG Rampage V Edition 10, G.Skill RipJaws V 4x 8GB DDR4-3200 CL14-14-14-34,
ASUS ROG Swift PG258Q, ASUS ROG Swift PG278Q, Acer Predator XB280HK, BenQ W710ST
I tried to reinstall the driver but it kept failing all components but the graphics driver, had to run a system restore just to get 3D back. I've been using 310.70 since it was released, and have had this FPS problem since I started messing around with the 3D Vision discover mode, months ago.
I'm using 1x Asus 670, power management mode seems to change nothing. The games I've noticed it in are mostly old: Black Ops 1, Black Ops 2, COD WAW, MW3, Fallout 3, TDU and maybe a few others I'm forgetting. In all of these FPS (without vsync) goes from being in the 100's at 80%+ usage in 2D, to the framerate becoming near unplayable and usage dropping. Changing the ingame settings as far down as they go doesn't fix it.
Anyone got any ideas? I'm really confused since as far as I know 3D doesn't measurably increase CPU load, so its not like theres a bottleneck. But my system is Windows 7, 670 2GB, i5 2320, 8GB RAM.
Thanks.
