Unreal Engine 3 on R420 at GDC

Why am i not surprised ?

 

chopiness smells like immature drivers more than crappy card...

Let me ask another question. Feel free to reject me if you think I'm too aggresive

Were the two systems running with the same content? i.e, not one with real-time rendering and the other with pre-rendered stuff?

 

The more pertinent question here is whether the two systems were that far apart in terms of performance.

 

If that's the only part of SpellSinger's claim that Daniel is prepared to refute, then it would seem that the only inaccuracy is in a detail. I doubt we will hear confirmation of anything beyond that.

 

I would say The crappy AMD system was a dual opteron 64 bit/winXP 64 and nvidia's was still 32 bits, sent by nv and EPIC didn't want to mess with cooling and/or PSU unit and left it as is, so that shouldn't tell us much. early versions of any engines are very CPU and memory intensive, and Tim has always stressed out how much importance puts on 64 bit computing.

Edit: even a single CPU would do if the OS was right and running on >4Gigs. choppiness is most of the times hard disk access.

 

This is simply not true: even if you have only 1 gigs memory like me I can't tell any game which chopping on my machine because of HD-access (I have Maxtor 15K SCSI hooked on a 29160)...

Choppiness is typically CPU-bonded symptom...

 

Ok stop and put some thought into it.

We are talking about a Next Gen engine. Not the Current Unreal engine. Your logic does not carry at all.

It could simply be a case of Drivers on the Nv40.

 

One would imagine that the folks and Nvidia and Epic talk to each other.

Surely if Nvidia was going to provide a system to Epic, they would ask what the best config would be to acheive max performance with the engine in its current state. AMD or Intel? Required RAM? preferred OS? etc.

 

Well Daniel then What is accurate? It either was faster on the R420 with higher resolution clearly noticable by the viewer or not.

Personally I am guessing that its a case of Pure FP32 simply being slower on the Nv40 hardware than the game running at FP24 on the ATi hardware.

 

1 This is an early alpha due 2006
2 My point was that it may not be GPU caused. Thank you for confirmation.

 

ooops...

Double post

 

OT: Hey, you're in Raleigh too..

 

So the other things are true? :?

 

Appears that way. He said the demo was running at 1024x768, not 640x480. That leads me to believe the rest is accurate. Unless, of course, he decides to clear it up.

 

Good, Ati owning Nv once more

 

Yeah, same feeling here...
