Newest Nvidia driver 378.49 causes memory leak

Just want to bring a little attention to this.
Several users have had a problem where the memory of their P3D v3.4 would just leak out and end in a OOM.
The nvidia driver which causes this is: 378.49.
I also have had this issue and I reverted back to 376.33 which is very stable and doesnt cause memory leaks.
I've experienced the memory leak on several routes (EFHK-EGLL 2x) (EFHK-EPWA 1x)
All is working fine now again.
Some proof that others have had this same issue:

How bad was the memory leak on our EFHK-EGLL flight?
Did you OOM?

I have been using this driver since 1-24-2017 without a problem.
Here is my test flight results using NVidia v378.49.
P3D v3.4.18.19475 hot fix2
EFHK-EGLL
EFHK RILB1N DEMIR UN872 EEL LAM3A EGLL
PMDG736
Took screenshots during the flight to track the FSUIPC VAS remaining.
VAS just before takeoff.
2102348
VAS at the gate EGLL.
1678248
Total VAS used on this flight
424100
All ok, great flight.

I also have P3D v3.4.18.19475 HF2, flew this route:
NUNTO Y369 REKDO N624 KOSKA DCT DEMIR UN872 EEL UZ701 GORLO UL980 LOGAN
I used the FsLabs A320, and I did OOM twice once over sweden and once just before entering germany

What do you think is causing the problem on your setup / add-ons?

Just as I said in the first post, it was the gpu driver. I dont have the problem with an older driver.

Looks normal to me. No problems here with the new drivers...

Have you contacted Nvidia?

I've been running these since release with no problems either. A very good driver all round for me in P3D and all my games, so maybe some other cause or combination for the OP.

I have the same issue as OP. 378.49 causes memory leak and any older driver fixes the issue for me.

Almost forgot, this memory leak with the nvidia driver 378.49 only happens to users of the 10 series nvidia gpus. Can OP confirm that he uses one of the new gpus? And others who do not suffer from the issue, which graphicscard are you using?

Same issue here with 2xGTX980Ti, new drivers causes memory leaks... rolling back to 376.33 fixed the problem
