Anybody have any ideas?

Turns out it was some weird incompatibility with Afterburner. Closed AB, and the test ran just fine. Test is buggy? thinking.gif

Anyway here's my result

I mean if you can't accept that... again, I don't know what to tell you.

As for that last line... all I have to say is, wat.

With a 4790k, though, your 290X will perform just fine in any DX11 title, while gaining even more performance over Nvidia's offerings in DX12 (which is not myth or anything; its coming). This CPU overhead issue is only really an issue at all if you are running an older or weaker CPU...

Must be a new dastardly plot of Microsoft's to get you off of Win7 and onto Win10!

Nice switching targets. No such thing as overhead. The drivers are just thread-limited.

You need a much stronger CPU to get the same FPS with an AMD GPU as an Nvidia GPU in many dx11 games at times of them being CPU limited. This has been very well known for almost 2 years at this point.

Nvidia is not exempt from the rules. Currently, only Nvidia avails two threads, instead of one that the driver can use; however that is not a clear definition whether those two threads suffice to deliver the performance you benchmark for. Consider than at any point in time you can have a cpu with a wider throughput at a single thread than another cpu's dual-threaded performance. "1 stronk > 2 weak cpus."
You can see AMD cpus and gpus are not that bad at 50 Hz. If you feel cheated, just up the ante a bit more than "medium" graphics. [Source]

Again lol (I don't know how many times this needs to be addressed), we aren't comparing dx11 vs dx12.

As for the rest of your post... again, I'm really not sure what you are trying to say lol... like at all. That benchmark (although seemingly messed up) does nothing but further prove my point....

Which is precisely my point. The whole reason this conversation came up was because I said if someone was using an AMD CPU I would probably recommend an NVidia GPU to them. If someone has an Intel CPU they are rarely going to get into any CPU bound scenarios, so it doesn't matter.
Sorry AMD

Whether the CPU or GPU bottleneck is most relevant to the screen resolution. Your statement is very vague and would only apply to a few certain situations at certain resolutions.

So in your opinion and based what you said would Vive actually be a better buy? (If we leave out the all Intel vs AMD thing)

 

I think it would really depend on what you are looking to get. I'd definitely think that the Oculus Rift controls more mindshare than the Vive, so there will probably be a bit more development effort on the OR than the Vive. However, I think the fact that the Vive can easily do roomscale VR out of the box AND also do seated experiences might be quite a draw too.

 

Then there is costs. Of which I think the Vive will actually be better pricewise than the OR, because HTC has many shipping channels all across the world to get their product in consumer hands. Whereas Oculus Rift is charging a kidney per OR for shipping. Not including the double whammy of that insane shipping again when they come out with their own motion controllers half a year from now.

 

However, the OR definitely has a bit better optics (slightly less SDE, and yes I've tried both). To me, the headphones make no difference as they sound like complete and utter poo compared to my Fidue A83s (which have beyond better isolation, and better spatial awareness due to being IEMs over headphones).

 

 

So the way I view it, pay for the full experience now? Or pay for it later? Kinda your pick. Both are solid units, and both have their pros and cons.

 

 

I'm personally waiting for Gen 2 at this point unless that new SAO VRMMO is released before gen 2, which if it does, there isn't a thing on this planet that is going to stop me from picking up a Vive or OR. But mainly I base this decision on my 20/10 eyesight in both eyes which makes the SDE still visible on both HMDs (sucks having TOO GOOD of vision sometimes :sad-smile). I'll wait for higher resolution displays in them, which by that point, there will also be better cards from Nvidia and AMD to drive them too.

 

 

Anyhow, hope this helps!

True. At 1440p or higher you are rarely going to cpu bound in dx11 games and probably not ever in dx12 games...

Thanks man!

One more question, as you mentioned the headphones, is it possible to use your own without messing something up? Im quite sure my Pioneers are able to out perform them as well.

I must say, that is actually quite impressive! I hope this hold true in actual testing...would really make for a great budget build for VR.
