Game sluggish and laggy after Ghost patch

I'm playing with Vive headset and Steam controller.

My game ran smooth before Ghost update, but after it it has had mysterious and distracting sluggishness. It's like the game responded to everything with a small delay, including controls.

This is especially bad when starting the game; for the couple first minutes the lag is worse. Inside seamoth you can also see how different parts render at different speed: when you turn the vessel fast, the environment and vessel 3D model first turn like you just turned your head, ie. the vehicle model comes into your view and then 2-3 frames later the vessel model is rotated accordingly.

The same can be seen with the diving mask to smaller extent - in fast head rotations the dials and mask come into view and then go away few frames later. (On plus side - this allows me to actually see the dials!)

This is not just distracting, but also makes game a lot more prone to motion sickness.

I have tried rebooting system and deleting the cache files to no avail.

System runs on i5-4670K and GTX 1080, so performance should not be an issue. Also: before Ghost update it ran smooth.

    Are you running from an SSD or a spinny (normal magnetic platter) hard disk? If it's a normal spinny disk, the first thing you'll want to do after an update is defragment the drive to get all of the files contiguous instead of scattered here and there across your drive platters. If you have an SSD, DO NOT defragment the drive, ever, SSDs don't benefit from that and it just wears them out faster. (Or, at least, only defrag like once a year or less - you won't see any improvement though, as SSDs can access any sector with equal speed as they don't have a magnetic head to move around searching for data.)

    I'm running on two SSDs, no spinning disks at all. That's the odd thing - the hardware does not have any immediate weak spots. I even have 24G of memory.

    Did you start a new game or are you running off of an old save?

    It's an old save. I have 70+ hours invested in it, I'm going to throw the game out of window rather than start from scratch.

    Hmm. Pretty odd. You could try parking it until the next update, I dunno what else to do, you've already tried clearing your cache. Unless there was a driver update or something that hit about the same time. You could check your logs to see if that was the case (I doubt it, it's probably just something bugged out in this update that'll be fixed next update).

    Ah, okay. Well, you can always make a new game to test with and keep your old one there. Of course, once the retail version comes out you'll have to give up your old game anyway.

    Sometimes... sometimes you just gotta let things go, man.
