problem with color

I just downloaded Verve and something weird is going on with my colours, if i use completly dry brush it paints okay, but the second i turn the fluidity number up. it paints only red. it goes from completly black all the way ti full saturated red. white also not available ...

Welcome to the forum, valera!
Sorry to hear about this, but what graphics card is in your computer?
I need this information in order to even begin thinking about what might be going wrong, you know.

Hello, Taran, thank you for a quick answer.I have notebook acer aspire v3 772g

windows 7
Intel® Core™ i7-4712MQ processor Quad-core 2.20 GHz
Graphic card NVIDIA GeForce GTX 850M with 2 GB Dedicated Memory

Woooot!
Please, download the latest driver for your video card, also, download Verve again (I did a small change)!
That MUST work fine! You have a really nice system, congratulations!

i updted my driver, weird, my geforce experience says i have gt 750m
i geuss i messed up on that it. should ve look harder on model specifications...
Its acer aspire v3-772g-747a8g1tmakk

NVIDIA GeForce GT 750M
Intel Core i7 4702MQ

with updated driver still doesnt work...

AH, that might explain it, though. The 750m is not a performance card...basically the low end Nvidia mulitmedia card, why ever they even made it, I don't know. It's data bandwidth is a 10th of the 900 series, for example, making it really rough on something like Verve or even games.
I'm afraid it simply can't quite handle that.

I don't know what else to tell you, as sorry as I am about that. ...Geforce GTX950M is supposedly working fine!

I wonder, if somebody else on the forum has any experiences with laptop graphics to make a good suggestion for an alternative? It's definitely worth it to scour the graphics card thread on here:

Valera, try the fluids on empty canvas (restart Verve before that). Can you see that weird result again?

Strange but….VErve runs pretty nicely on my Nvidia 650m with only 1 gb ram on my 2013 macbook pro under bootcamp/windpws 7

Thing is, we don't really know what is happening. It's so hard to diagnose an issue, when you can't quite tell what's going on. It does look like a shader issue, but then all the rest of the shaders seem to work just fine. The only other thing I could remotely imagine is if there was some other openGL application running that would take away all the memory OR (and that's a really big OR) something is literally broken with the card...maybe a broken memory piece?
I don't know... but it sure is weird.

Possible it's also just a bad use of the Verve functions!
Sometimes we are losted in a labyrinth of Fonctions / Shortcuts and better is restart than try to refind the exit!
