GTX980Ti vs GTX 1080

Recommended Posts

Is there any reason in P3D v3.x  to upgrade from a 980Ti to the available 1080 cards? Given the cost will there be any noticeable increase in performance? For reference, I would consider a 10% frame rate increase to be clearly noticeable. 

 

Sorry if this has been asked already, and thanks for any input you can give!

I went from a 670 to a 1070 and saw a 10FPS gain...I was using 4 monitors.

 

In your case I doubt you would see any gain if at all.980ti is a good card.. If I were you, I'd wait

For P3D get 2 video cards and Rift.

 

Trust me we simmers have almost the entire hardware requirements for VR.

 

Skip 980ti and go for 1080 or 1070.

 

I believe 1070 outperforms 980ti.

 

2x1070 will be nice with VR and P3Dv3

 

P3Dv3 loves SLI.  It works so much better.  And I have 2x980s

Use a GPU utilization monitor and see how close to 100% utilization in your general flying scenarios. If you're never reaching 100% (I don't with a 980 @ 4K), then you probably won't see any improvement if you move up. You can also check your VRAM usage.

Apart from the gain that can be expected: maybe you have very good eyes but most people can't see a difference between 30 or 33 fps. Or 40 and 44. Or 50 and 55. And so on. An increase of 10% isn't much, it is in fact very, very little, specially not for the price of a GTX1080. I wonder if anyone else would consider a 10% frame rate increase clearly noticable.

Not at all. Keep your Ti until P3D evolves in a way that justifies it.

 

The 980 Ti has insane memory bandwidth (more than a stock 1080) and that really helps in high resolutions, leaving the "equivalent" 1070 very close or even behind in P3D.

Thanks friends. I was just looking for a reason to spend money uselessly and you saved me! My head told me there wouldn't be much increase, but you know, we always are lured by the shiny new thing.

I have the TI and P3D doesn't use most of it so I see no point in upgrading at this point, I'm running the ASUS Strix edition which is a pretty good TI and on the 1440p ROG Swift monitor.

Only reason I'm upgrading to a 1080 was because I'm replacing a gtx 580. Now that's an upgrade!

Or you could spend $1200US on a new Titan X (Pascal) and still not see much improvement over a GTX 980 ti. Until P3d goes DX12, the CPU side of things will be limiting what nVidia's top of the line cards can do.

I have a GTX 780 and it seems it might be worthwhile upgrade, but I don't know what benchmarks to compare with.  Any hints, yea or nay?

What monitor are you using? Do you have multi monitor setup? If you do then it maybe worth replacing the 780... otherwise you may want to do more research to see how your could benefit ...

 

I wanted to say, you could benefit with more denser clouds,..but with the v3.3.5, LM gave us a improvement on that front as well

It depends on the setup indeed. I have a 1920x1080 monitor and a GTX780 (6GB) and tried a GTX980Ti last year. Send it back to the store the next day. Not worth the money at all.

Just a single 23" monitor...Though I have 19" crt in the basement, but no desk space nowadays.  I want to get more monitors some year...

In that case: if you want to give the 1080 a try, make sure to get it from a store where you can return the card no questions asked. ;)

 

And btw concerning the benchmarks (which was your original question): P3D can't be compared with ANY game out there so unless you find a benchmark done with P3D itself, benchmarks are of no use at all. In a lot of games the difference between a 780 and a 1080 will be staggering but not so with P3D.

Really good advice, J van E. Mainstream benchmarks don't reflect the CPU bound nature of P3D.

I have been flight simming  for years, I change a graphics card every 2 or 3 years and always ask the question in forums, will upgrading to the latest (in this case 1080) from my current (780 in this case) make a difference?

 

Always get the same reply, no it wont, wait for the next generation card , what that does is slow me down from buying the card inmediatelly , then like a month or so later I go buy it, install it and every single time I have been happy with the results.

At this stage Im in the month of thinking about it.

From my experience the jump 980ti > 1080 in P3D will be rarely noticable. It could even be that 980ti performs better. It is a great card. Only for P3D, the jump to a new card is not worth it.

 

If at all I would wait for the 1080ti and ask again!

P3Dv3 loves SLI.  It works so much better.  And I have 2x980s

 

Interesting to hear that P3Dv3 loves SLI.

 

I remember when lots of discussions were going on in here on this topic and I remember there were all kinds of issues in the beginning where people had weird problems with lights, P3D didn't make full use of the second card with a very uneven load between the two cards etc etc.

 

However after reading your comment I take it all these issues have now been addressed in the latest version of P3Dv3 and that it's now able to make full use of an SLI setup without any issues vs running on a single card? Have Nvidia finally released a proper SLI profile for P3D?

 

I'm on a single 980Ti as well but my question/interest wouldn't be if an upgrade to a 1080 would be worth it but rather getting a second 980Ti now that you can get one for half the price you paid for your first card if you bought it when they were released like I did.

 

Doubling the graphical power in your rig for about $400 seems like a rather good investment in my eyes as long as the most current as well as furture versions of P3D will make good use of it without causing any issues related to SLI.

From all I heard is that SLI will NOT double graphics power. The bottle neck is somewhere else.

No, I guess that is right.

 

I did some searching after posting in this thread and looks like the experience people are having still is very mixed. Some say SLI works really great in P3D like in the post I quoted in my last post while others say quite the opposite and some people say they get even better overall performance running a single card.

 

I also confirmed there's still not an Nvidia official SLI profile for P3D.

 

So...with this said I'll carry on with my single 980Ti for now.

There is a SLI profile with the Nvidia Drivers for a while.  I see Prepar3d in Nvidia Inspector and Nvidia Control App.

 

I even tried with SLI indicator on.  So far super awesome on my end.  Ask Rob, I believe he is using SLI too.

I know there has been a Prepar3D entry in the Nvidia driver list for quite some time but the way I understood it that one never really worked very good with the current versions of P3D. I followed the link below listing all games with true SLI support and I couldn't find any version of P3D in that list.

 

Anyway glad to hear you're happy with your SLI setup :smile:

 

Here's the link showing games with SLI support mentioned above.
