334.67 is known to be broken. the problem is reproduced by nvidia so maybe next update/beta.
this change a top there just breaks opencl, so madvr isn't even trying to use it anymore, so no black screen but no opencl too just broken opencl plz make sure didn't try this anymore thanks.
reproduce in doom9 madvr thread.
Tested by many @ doom9.org.
No increase of CPU/GPU usage at all.
NNEDI3 functions do not work at all (although do not freeze/black screen).
It just bypasses OpenCL completely, hence not apparent side effects.
The dithering you see is just normal random dithering with openCL bypassed although looks like OpenCL error diffusion is activated... Its not.
This is the Official (the one and only) thread:
There are combination of settings that give (me) a perfect picture *:
* No Elevated Blacks, No Black Dithering Noise, No blue whites, Perfect color, Perfect Gamma Curve.
I have tried all combinations of these:
2.2 Relative - Absolute Colometric = Blue Whites.
2.2 Relative - Absolute Colometric w/ White Pouint Scaling = Blue Whites, Extended Grayscale.
2.2 Relative - Absolute Appearance = Good (Colors/Gamut not perfect).
2.2 Relative - Relative Colometric = Elevated Blacks.
2.2 Relative - Luminance Matched Appearance = Perfect.
2.2 Absolute - Absolute Colometric = Blue Whites.
2.2 Absolute - Absolute Colometric w/ White Pouint Scaling = Blue Whites, Extended Grayscale.
2.2 Absolute - Absolute Appearance = Good (Colors/Gamut not perfect).
2.2 Absolute - Relative Colometric = Elevated Blacks.
2.2 Absolute - Luminance Matched Appearance = Blue Elevated Blacks...
If you guys have problems in MadVR with Dithering and noise in the blacks try the one setting.
Of course you can use any gamma you want (2.4) or Apply Calibration (I use windows so its always on).
Note that my calibration (Asus Gamma 2.2) is a pure power curve (Gama 2.2 Relative) with Black Offset 100%, Black Point Correction 0%, Profile is default Curves + Matrix.
I think you can calibrate to MadVR preset, BT.1886 & LUT Profile, I don't think it matters.
I do not use MadVR for calibration or the BT.1886 setting in argyllCMS, I found that the standard Gamma 2.2 Relative gives me the most pleasing and balanced results for my monitors without extra hassle (these settings are standard for a reason).
Try and tell me what you think.
Double post... but things are going slow lately anyway.
I want to use the "Measurement Report" in DispCalGUI with MadvrTPG...there are few disabilities so that I can't get the results I expect,
My goal is to compare the MadVR 3DLUT or yCMS with the Rec.709 color space, THATS IT.
Is there a simple way to use MadvrTPG to show the colors with the already set Calibration parameters in MadVR settings?
For example: I want to compare the yCMS LUT I have created with rec.709 color space... Just the color space (Gamut)... But I CAN'T.
Well that does it...
I can't generate a MadVR 3DLUT that doesn't change my perfectly good calibration curve.
All that I've tried enforces me to use BT.1886 which I DON'T WANT !!!
I just want a gamut correction to rec.709 and leave my calibration (greyscale) alone.
Graeme, Florian, why is it still not possible?
I already have a perfectly good calibration+profile ICM with Gamma 2.2 Relative.
I now need to convert it to 3DLUT without changing the Gamma curve only the Colors.
Thank you, but it does not work. It still changes the gamma curve to some extent.
Turning off BT.1886 raises the gamma to extreme, making it super bright (as expected from the REC.709 profile).
On the other hand, when selecting BT.1886 2.4, the gamma is correct at the shadows but darkened at the middle.
There is no option to leave calibration as is.
When I load the 3DLUT into MadVR I see Gamma & Color change, I want to see ONLY Color change.
FWIW I don't want a "pure" gamma curve, I want MY gamma curve from the calibration I already did (carefully tweaking the Black Offset & Rate).
Meantime solution I use: BT.1886 2.4 & lower the gamma to 2.05 in MadVR.
