I saw that the first test version of this new renderer is available in the latest update.

But why is it slower than the dx9 rendering? I thought it's supposed to be faster since dx10 was a complete redesign/rewrite of dx. Is this because you're still working on adding full support for it or will it stay slower?

I was little surprised that dx10 turned out to be slower, I'm not really sure what's the cause of this. but even simple things like clearing screen, or drawing fullscreen quads are slower than dx9.

My guess is dx9 is available since long time and graphic drivers are more optimized for it, or maybe just dx10 requires gpu to do stuff with some more precision, and that's why its slower.

Dx10 performance in EE will mostly stay that way, but as for dx11 I'll try to make some additional optimizations once I get a new dx11 gpu card.

I've did some small research and in most of game benchmarks that I've found, the DX10 is always slower than DX9 version. However it's hard to tell because some games add more features in DX10, so it doesn't need to be an equal comparison.

Here are some links to what I've found -

I think that the last one makes a clear comparison of DX9/DX10 (set of features is the same, however DX10 is always slower)

In my project DX10/11 is faster than DX9 but I don't know why.
FPS in my game:
Sync ON:
DX9: ~15fps
DX10/11: ~59fps
Sync OFF:
DX9: 20-25fps
DX10: 85-90fps

maybe you use some effects which aren't implemented in the dx 10 renderer yet.
What's your graphics card btw?

that's weird, basing on your scene looks like dx9 is too slow,
have you ever installed some debug graphic drivers or debug directx9 runtime? these things can slow down things

Would you mind showing some pictures of the new tessellation functionality? I'd love to see a perfectly smooth/round surfaces in EE!

I would like to join to the Masterxilo's request and ask could you show some differences between dx9/dx10 rendering if they are (my computer actually handle only dx 9 :()

sure, I'll try to make small demo and record video+screenshots
Harry - DX10 looks mostly the same, the only benefit is that you can have alpha to coverage to make trees and grass to look more realistic (only in super sampling=5 or multi sampling on DX10.1)
grass and leafs seem more transparent

I've added DX11 Tesselation demonstration here - http://www.esenthel.com/?id=news

and I've put the info here - http://www.esenthel.com/?id=feature/rendering
you can see better the alpha to coverage difference when moving the mouse over the image on that link

That looks awesome, will have to upgrade again now

Thanks It looks great.

Great work... really really great
