Introducing Warp3D Nova for AmigaOS 4.1

[Spectre660]

Running Gears3 from Minigl Demos results in 100% cpu  use.
Running Warp3D Nova Gears results in 12% cpu use  .
Idle system is 5 % cpu use.
Sam460ex RadeonHD 7750

The Warp3DN Logo demo maxes out at 62% of cpu use .

[Spectre660]

The Minigl demos are using Warp3D.
The famous cow3d demo using warp3D also results in 100% cpu usage .
Will be interesting to see what happens with a Warpd3D nova version

thats anyway quite a high resource demand for such a simple demo.

[Spectre660]

The CPU load utility seems accurate .

sounds suspicious, dot you think? maybe there is some busy looping in a driver or synchronization or whatsoever. what happens if you run further applications alongside? maybe simply that cpu load utility is wrong?

[Spectre660]

Cow3D gives about 114 FPS.

CPU usage without the actual framerate doesn't say a lot. You can produce 100% CPU usage drawing a single triangle at 1000 FPS.

[Spectre660]

Ok. I am not running Candi.But I don't know if any of the Warp3D Nova demos give any FPS
information .

Sure, but Cow3D is a Warp3D program. My point was, that the Warp3D Nova example programs by themselves, without CANDI running, locked at a sensible framerate would probably consume very little CPU power compared to Warp3D. CANDI can skew the results, since 2D Compositing API is still very CPU bound.

[Spectre660]

Yes there are two separate libraries .

i was miss leaded at the beginning by the name of the package containing "warp3d" and that it was suggested being an upgrade to the previous warp3d. now i understand that it is completely different library the applications need to be particularly compiled against. existing warp3d applications wont take any (speed) advantage of it.
so there is now warp3d.library in the system and some other library for warp3d nova functionality alongside?

[Spectre660]

I was not "expecting" anything just trying to demonstrate that the new driver uses much less cpu resources than the old Warp3DSI driver.

The supply of compatible Radeon HD Southern Islands cards is shrinking so
he who hesitates may be lost.
I got a pair on HD7750's  almost two years ago and I am glad that I did.

thx for confirmation. maybe it should be clarified. i have the feeling, users rush now for warp3d nova supported cards, expecting some immediate improvements, even with the existing software, as spectre did in his post about cow3d. perhaps it would be better to hold off till the package is actually released and at least a single actual application is available for it. this might be a better publicity policy in a long run, while avoid disappointments on part of not so well informed customers.
