New Unreal Engine 3 Trailer

Oh, so it's multithreading synchronisation with the GPU. But once again, they need to utilise it first, it doesn't just come out of the blue with DX11. And doing so might be difficult for an engine as big as UE3.

It's not to be confused with the coarse multithreading we've already seen. Some games have even used command buffers like Metro 2033, but command lists are new on PC, and are much faster.

That's what I was getting at with the Epic Samaritan GDC demo with people gasping at the tri sli GTX580(?) to run that DX11 demo. Because we no nothing of optimization and whether a game(if they actually make one) would be using the full DX11 feature set, such as command lists. It may well be possible to get similar performance on a lesser HW , we simply don't know until DX11 multithreading is more widely used.

I seriously want that Samaritan demo made into a game.

DX11 multithreading (command list enabled) drivers weren't available ,until now.This should hopefully go some way to ending the CPU -DX API bottleneck as more studios implement this.

So far that's just on NVidia drivers. AMD's got some drivers hitting presumably later this month which are offering fairly high gains on a number of DX11 games like Civ5, suggesting they're probably doing the multi-threading thing as well.

They're even offering them as a preview right now, and I've been running them since the beginning of this month.

Haven't played Civ V with them, though...

np: FaltyDL - Our Loss (Love Is A Liability)

I wouldn't be surprised if it's something they're working on. They did tech demos with GoW and Infinity Blade assets in the past.

I don't have Civ 5 either ,just one thing about this if you do get it I noticed this :

...you go to the "Sid Meier's Civilization 5" folder in your "My Games" folder and inside you'll find a file called: "config.ini", open it up in notepad and find the command: MaxSimultaneousThreads = xx, then change the "xx" part to any number from 2 to 16, depending on what # of CPUs you have. You should also check the "GraphicsSettingsDX11.ini" file in the same folder to make sure DX11 is correctly enabled with this settting: "AllowSM50 = 1"

I have Civ 5 all patched up and maxed out in game, but when i checked these two settings the multithread setting was on 2 and AllowSM50 was set to 0, after changing them to 4 and 1 i saw a nice performance increase

Obviously if you've got an i7 that'll be set to 8

Might be interesting if someone here can report back fps before and after.

Mmmm, love the music.
