Recommended specs for best performance?

[MoP]

Hey,

So I bought the beta of Substance Painter yesterday as I have been enjoying using Substance Designer for a short while now and wanted to see how the painting app is coming along.

I had seen demos from the Allegorithmic guys before (running on a laptop!) and the performance seemed pretty good for painting.

However since I have installed it and tried it today, even a very simple brush (default soft circle, diffuse channel only, no other channels to paint) on a low-poly mesh, it is extremely slow to update on my PC (keeps saying "Computation in progress" after every stroke). It's basically unusable for a natural feeling painting, for me.
The default smoke particle brush takes more than around second to update each iteration while the texture is being applied!

I know my PC isn't the newest - it has the following specs, compared to the minimum/recommended specs on the Steam app page:
- Intel i7 920 2.67GHz - (no processor spec listed on app page)
- 6GB GDDR3 RAM - (4GB recommended on app page)
- Geforce GTX 275, 1GB / DX10 - (1GB / DX10 minimum, 2GB / DX11 recommended)

So as far as I can tell my graphics card is at the low end of the recommended spec, although the CPU is pretty dated too but given there is no baseline recommended, I can't tell if that is part of the problem.

My two questions are:

1. Would you expect a PC with this spec to perform unusably slowly when running Substance Painter? Could there be something else going on here (outdated drivers, not enough HDD space, etc. etc.?)
2. What graphics card (and CPU if necessary) would you recommend to get smooth, natural-feeling painting performance out of the app at this stage?

I'm assuming that with suitably powerful hardware, the painting will be responsive and smooth. It's about time I upgraded anyway...

Cheers,

Your GPU is too slow as far as I can tell. GPU is key with Substance Painter, as most of the work is done there. Go Titan if you can!

Yeah, that's what I figured, Sébastian.

I just tried it out on my work PC at lunch time (GTX 670 with 4GB VRAM) and it's super smooth.

I guess it's time to upgrade at home! :)

The PBR shader is for the moment very heavy, so having a good GPU is important. For those who have low perfs, you can try to paint on single channels instead on all of them. You can change those settings in the "Viewer Settings" window.

Does Substance Painter give preference to Gamers cards over Workstation cards? GTX over Quadro, Radeon over Firepro?

[alexis.khouri]

Quadro is always trcky to handle, but GTX, Radeon and Firepro should work fine

[alexis.khouri]

GTX 570 should be fine :)

So, something like this > http://www.newegg.com/Product/Product.aspx?Item=N82E16814195116&ignorebbr=1 < wouldn't melt Substance Painter? I mean, assuming I ran into a bundle of cash in the next couple years. It handles 32TB texture files... and I'm sure I'll need that someday, lol.

Thanks much
