How's the performance of the game?  How well will my 980 Ti be able to run it at 4k?

Running a single T-X and 3770k @ 4.2 at 4k and to get it to play  smooth for the most part I had to turn off AA completely,  put godrays on low (which doesn't make much difference anyway) and set shadow quality/distance to high. All else is maxed/ultra. Of course the frame rate does what it wants when it wants some times, such as tanking in a closed off corridor but peaking while looking across the waste during the day (???).    

Was running great here, 100-120 FPS ,  this morning I had a game update when I started it for the first time since yesterday morning. Now getting random crashes. Not sure whats causing it yet
 

I haven't really checked my FPS but the few times I glanced over it was 71 or higher. All settings on Ultra at 1920x1080 144 Hz and everything is smooth. No crashes like Fallout 3 yet. It seems pretty stable to me. Once or twice I got 'stuck' and had to load a previous save to get going again. I save quite often just in case of these things.

I've been primarily playing it on the Radeon side of the fence. Not a single driver stability issue with 15.11. As with all experiences, mileage may vary. 

It plays at a solid 60 FPS (V-Sync enabled) for me at 1200P at High (autodetect).

I plan on getting FO4 but once I get a new pc. Done trying to play newer games on this Alienware. Too many issues.

Yay!!!  I was able to get it.  Just finished downloading it.  Getting ready to start after I update drivers.

Heh I ran that can I run it thing for FO4 and my pc and yep my pc is definitely in need of replacement before I play newer games like FO4. I very much want to play this game so badly.

i got flames!

Don't spoil the game by running it on something that can't make the grade. I'm running a 770 classy and I have a choice. Reduce some settings or buy a 980 TI SC. I am serious when I say it is worth the upgrade.
