Got my new GPU today, made some tests and here is what I found:
Test 1.
GPU: RTX 2080 Super
Optix acceleration enabled
Graphic driver: 435.80 gameready
Optix version: 7.0.0
DAZ Studio 4.12 (64-bit) Public Build +BETA+
Render settings:
Max samples: 1500
Firefly filter on
Post denoiser start iteration 1498
Render quality: Disabled
Coverage: 95%
Spectral observer: ciel1964
Render time: 22.24 minutes.
Test 2:
GPU: RTX 2080 Super
Optix acceleration enabled
Graphic driver: 435.80 gameready
Optix version: 7.0.0
DAZ Studio 4.11 Pro (64-bit)
Render settings:
Max samples: 1500
Firefly filter on
Post denoiser start iteration 1498
Render quality: Disabled
Coverage: 95%
Spectral observer: ciel1964
Render time: 25.24 minutes.
Test 3:
GPU: GTX 1080
Optix acceleration enabled
Graphic driver: 431.70 desktop
Optix version: 6.0.0
DAZ Studio 4.12 (64-bit) Public Build +BETA+
Render settings:
Max samples: 1500
Firefly filter on
Post denoiser start iteration 1498
Render quality: Disabled
Coverage: 95%
Spectral observer: ciel1964
Render time: 55.57 minutes.
Test 3:
GPU: GTX 1080
Optix acceleration enabled
Graphic driver: 431.70 desktop
Optix version: 6.0.0
DAZ Studio 4.11 Pro (64-bit)
Render settings:
Max samples: 1500
Firefly filter on
Post denoiser start iteration 1498
Render quality: Disabled
Coverage: 95%
Spectral observer: ciel1964
Render time: 53.06 minutes.
In short:
New GPU RTX 2080 Super best render time = 22.24 minutes.
Old GPU GTX 1080 best render time = 53.06 minutes.
New GPU with Daz Studio 4.12 beta = 22.24 minutes.
New GPU with Daz Studio 4.11 Pro = 25.24 minutes.
Old GPU with Daz Studio 4.12 beta = 55.57 minutes.
Old GPU with Daz Studio 4.11 Pro = 53.06 minutes.
So using the beta and the new GPU provides a speed boost over the regular Daz Studio version.
But seems like the Daz beta makes the shadows softer, I guess the shadows are handled in a different way and they require tweaking the render settings.
