You might want to try using an appropriate LUT, slog 2 and slog aren’t siblings so much as cousins. They don’t share LUTs.
Heres one from Andy Shipsides, which might be useful.

I’ve got several of both cards. They are different classes of chips, the Titans are GK110, 690s are GK104. The 690s are basically two slightly slower 680s sharing one board.
The advantage of the 690s is the combined processing of multiple GPUs, if you’re running in a MacPro for example, and you put in one 690 and a GT120 or similar for GUI, using a full resolve license, you’d basically have the equivalent of 2/3rds of a cubix with three 680s available to you. Without having an external chassis.
The disadvantage is that the 690s only have 2GBs of RAM per GPU. This can become troublesome for larger image formats.
The Titans on the other hand are based on a different chip. Which as I mentioned doesn’t have driver support on the Mac, but which has a significant processing improvement over the GK104, as exhibited on my Resolve linux system. Even better though is the 6GBs of RAM, which not only seems to improve performance, but also reliability with large images.
But like I said, in terms of performances, 1 Titan = ~1.5 GTX680s (plus lots of ram), where as 1 690 (meaning two seperate chips on the same board, with both chips working together) = ~1.8ish GTX680 (with a limited amount of RAM). On the Mac, once you get into expansion chassis the 690 looses it’s advantage as you can only address 3 gpus on the Mac, and each 690 is two gpus. So with two 690s you loose half of one card. Titans on the other hand offer great performance and are only address as one GPU, so on systems that support it are ideal for an expansion chassis.

“Anyone put them up head to head in resolve?”
Yes. The Titan is about 50% faster than 680. It’s about 85% as fast as a full 690. If you’re using an expansion chassis doing high res work. Higher than 3K. Then the Titan is your best bet. But it doesn’t work on the Mac. Works fine on windows and Linux though.
“Anyone know of a flashed bootable version?”

I say take it all the way to 11. All the time. 😉

Latency. It’s definitely incredibly promising technology, and probably the future of 3D rendering and maybe video compression (among countless other applications). But resolve is very much an on demand sort of processing application. That said, NVidia has some insanely fast cards out now, the 690s and Titans are both Resolve beasts.

Yes. Ive done it. It works. Just select the supported format in the output settings.

Best is to remove speed effects and then recreate after grading. With the latest versions, speeds usually come across correctly, but not always.

Are you reading and writing to the same drive? Might try going to a seperate drive for more consistent speed.

There were different LUTs in the previous version of resolve. The current version has two LUTs, one for P3, which does not change the gamma, and one for 709 which does.

It isn’t sufficient. Stick a gpu in a 4x slot and see how well it works in resolve.
