Closing Thoughts

We're still early in the release cycle for Civilization: Beyond Earth – in fact, our testing was done with pre-launch code, and there's already talk of a day zero patch to fix a few glitches (e.g. with multi-GPU configurations that have more than two GPUs) – so by no means is this the final word in performance. It's not too surprising to see NVIDIA's GTX 980 taking the single GPU performance crown for Beyond Earth, but additional driver tuning may change things a bit. AMD also had a slide showing the R9 290X 8GB edition leading the GTX 980 in performance (with Mantle at least). Hmmm....

The good news is that if you have any reasonably modern GPU – from the GTX 770 and R9 280 (nee HD 7950) – you should be able to run at 1080p and High or even Ultra quality settings. Lesser GPUs can still handle the game as well, and if you're curious it's possible to get frame rates well over 100 FPS even at 1080p if you drop to lower quality settings.

As for Mantle, it's an interesting option if you have an AMD card. While we're not seeing any huge benefits on our test system, it does typically run 5-10% faster than the DX11 path; this is good but in most cases it's not enough to really make a palpable difference to the end user. The word is that lower spec CPUs like the Intel Core i3 and Pentium Anniversary Edition along with AMD APUs can benefit even more. I'm not sure how many people are actually pairing up slower CPUs with high-end GPUs these days, as $200 CPUs are pretty common for gaming systems, but additional options are never a bad thing.

Mantle does have a much more tangible impact on minimum frame rates, and this is always beneficial, particularly once a game is averaging more than 60FPS. In some cases Mantle was able to improve the minimum frame rates (e.g. on R9 290X) by 40-50%, though that was only at less strenuous settings. Still, even the 5-15% increases in minimum frame rates at higher resolutions are welcome. In some cases, Mantle is the difference between AMD's "equivalent" GPUs trailing versus leading NVIDIA's offerings.

Then there's the subject of Mantle and CrossFire performance, which I've now finished retesting. Mantle generally means more work for the developers when it comes to multi-GPU configurations, but with the appropriate effort the results can be quite interesting. Firaxis has chosen to implement a custom SFR mode for CrossFire on Mantle, though at present the only way to enable SFR is to manually edit your configuration files. (Why!?) The result of CrossFire and SFR in our benchmarks is substantially higher minimum frame rates than the D3D11 AFR rendering mode, and average frame rates are also improved relative to a single GPU.

As far as the game itself is concerned Civilization: Beyond Earth looks like it will prove every bit as addictive as the earlier releases. Now that I've done a ton of benchmarking with Civilization: Beyond Earth, I need to find some time to actually play the game. My birthday is coming up next week, so maybe I can get some free time as a present…. Then again, birthdays only last 24 hours and if past experience is any indication, I might need more like a month to get Civilization Fever out of my system. ;-)

    I think that You make good point about $$ on CPU vs $$ on GPU... for now.

    Cause if Mantle can let us spent $$$ less on CPU then, why not?

    (That ofc. would require more widespread support in games.... Or DX12 Or OpenGL AZDO)

    Not necessarily. Civilization V was a cpu limited game for the most part. Reply

    indeed, Civ V was a great CPU benchmark (akin to Supreme Commander), and the performance scaled quite well with added cores... Reply
  • SuperVeloce - Friday, October 24, 2014 - link

    Civ V scaled well with up to 4 cores if my memory serves me right. Not much more with 6+ cores. Reply

    I was playing civ5 this past week while waiting for the new game... and you know... even on my 4790K it bogs down on big maps. Reply

    Especially as turn time and not FPS becomes the limiting factor late into the game. Anything above 20fps is decent, but if turns take a minute then it's intolerable. Reply

    Min. FPS should be tested as it's more important than average when almost all cards demonstrate more than playable performance even at 4K. Reply

    "the built-in benchmark basically represents something of a worst-case scenario for performance"

    I have logs including minimum FPS, but time constraints kept me from spending too much effort analyzing them. What I can say is that when the game zooms all the way out during the benchmark sequence, that's when the minimum occurs and it's usually around 2/3 of the average FPS. GPUs with less VRAM may also be hit harder though. Let me see if I can add some charts for minimums, now that I've managed to get some sleep. :-) Reply
