Why has Nvidia just discovered these new ways of getting massive boosts from simple driver updates after AMD just releases a way of showing Nvidia up? I just feel we could have all enjoy much better performance alot earlier, but Nvidia just holds back what they really can offer us and just release what they have to. This if anything is great for their pockets so they can keep pushing out slightly improved products to stay that little bit ahead, but is bad for developments and pushing what games can provide.

I suppose we should be happy though

 

I'm just happy about Mantle lol, this pushed Microsoft DX12 and Nvidia to work on it. There is always room for improvement.

wait so nvidia will get mantle? Im confused. Also when do these new drivers come out?

It's not like it's baseless. Nvidia's advantage when it comes to CPU overhead in DX11 has already been shown to be there by multiple reviews. You have to be using windows 8 though to see the improvements.

Remains to be seen how much these new drivers will improve the current situation though.

But nvidia graphs are with windows 7

They are pr graphs like amd's one. Even my 7970 can get more than 30 fps on star swarm and 55 fps on thief

You’ll find DX12 support on Fermi, Kepler and Maxwell parts
Quote:
The Draw, SetIndexBuffer and SetVertexBuffers functions have gone through several hundred percent performance improvements since just the R331 driver stack to an as-yet-unreleased driver due out in the next couple of weeks

That is massive. A 4x draw call increase and completely solidifying Fermi. I can think of many games that will be insta-fixed with that draw improvement.
Quote:
we will only really see these improvements surface in titles that have addressable CPU limits or very low end hardware

Missing it a bit PCP. You don't need a 780Ti or another high end GPU to see that when many games fall below 60FPS it's CPU reliant, no mater Ivy-E or Phenom II. This will also help give some validity to 120Hz.
post #17 of 203
There's only about a 15-20% performance boost going from the GTX 770 to 780. That's 1536 cores to 2304. That's 50% more cores for 15-20% performance boost.

I know there is more performance left to be had, and it looks like nvidia may finally be willing to give it to us.

Well maybe it's just BF4 that shows huge improvements going from win7 to win8. It's just that BF4 has been the most benched game recently and it's also somewhat CPU limited so I assumed it was representative.

So it's really hard to find examples of anything else.

On star swarm it depends on what scenario you run. I remember back in some of the mantle threads we did some testing with a couple of users. With the most consistent mode it seemed like AMD 290Xs/290s were in the 30fps range.

Dunno about thief since I don't own it.

Also gotta take clocks into account...
