*some progress*
A very nice article on Far Cry 4 performance has been out for a few days, over at
HardOCP. The game has been applied the latest patch (1.6), and gives some ideas on what to expect from various video cards.
Overall, the latest generation Maxwell GPUs perform better in Far Cry 4. With all the Kepler GPUs we tested, GTX 780, GTX 770 and GTX 760 these all performed rather poorly. We had to sacrifice many in-game quality settings just to find a playable performance. With the GTX 970 and GTX 980 though we were able to maintain higher settings.
We also found that some AMD GPUs are even superior to Kepler GPUs. For example the AMD Radeon R9 280X and R9 270X performed a lot better than we had anticipated. Both GPUs beat the NVIDIA competition in this game. However, the opposite is true for the R9 290 and R9 290X. Those two GPUs cannot at all keep up with NVIDIA GTX 970 and GTX 980 in Far Cry 4. These are underpowered in this game and are beaten squarely in the face by the GTX 980 and GTX 970.
When it comes to the high-end GPUs, again GTX 970 and GTX 980 is the way to go. GTX 970 is probably the best value, which is able to beat out the AMD Radeon R9 290X even. Overclock a GTX 970 and it should do even better. You will be able to play at 1440p with the GTX 970, but you won't be able to max out the game. Even the GTX 980 cannot max out the graphics settings. This game will need even more powerful GPUs to max it out at 1440p, or SLI can do that as well right now.
The GTX 780 and 770 are bad for this game in terms of performance. You'd be better off with the AMD Radeon R9 280X which will offer a better experience compared to either of those video cards. Compared to the GTX 760 the AMD R9 270X would also be better.
In terms of low-end GPUs you'll actually find a bit faster performance with the R7 260X versus the GTX 750 Ti. However, both are still very slow and you'll end up sacrificing either in-game settings by a lot, or having to reduce resolution to 720p to maintain good image quality in the game. These two video cards are just too slow for this game, you'll need to aim for a better GPU to enjoy this game.
Running Far Cry 4 at 4K is very demanding, and only GeForce GTX 980 SLI allows a decent experience. It still cannot max out the game settings at 4K, but right now it comes the closest to doing so since CrossFire is broken. There is no way you'll enjoy this game at 4K with a single video card.
As for me, I finished playing the campaign yesterday at 75% on my Asus Top GTX 670 2GB (4770K @ 4.3 Ghz HT Off + 8GB RAM + Intel SSD). I had everything on Ultra (Enhanced God Rays, Soft Shadows and SMAA) at 1680x1050. I usually don't play with AA, but SMAA made the scenery look so much better, so I had to keep it for a small performance hit. For the most part I have averaged between about 45 to 60 FPS (Vsync On with Triple Buffering) with very occasional frame drops to about ~25 FPS. Have not experienced any stuttering whatsoever (maybe SSD helped with that), input lag or whatever other people have been reporting, everything was smooth and bug-free. Not a single exit to desktop, perfect. Can't say how it compares to my 270 CF as CF support still non-existant, but I agree with the article above, 270 runs fairly well. Also, the game proved to like 4 cores with HT disabled. The game ran fairly well on my other rig with X5650 equipped w/ MSI R9 290 GAMING (friend is busy testing it). That one also felt better with 6 cores @ 4.0 Ghz and HT off, but the AMD card didn't feel as smooth at times, but clearly more powerful.

Some of the settings above may read Low or High, but these are not selectable from the game menu, so I left them unchanged. Maybe they give additional eye candy but I've never bothered to check and compare. Really, not that picky. Just so you know.
I recommend playing this stupid game to everybody. It has
good moments and lots of fun. Also as it appears, it does have an alternative ending, just be patient.
