Hardware Accelerated Rendering benefits

Recommended Posts

Hey guys, was just curious as to the benefits i have with / without hardware accelerated rendering. I would generally assume it would be beneficial but im not 100% so i thought id ask for some opinions

I have a well cooled desktop machine with an i7-4790k clocked at 4.28ghz, 32gbs of ram and a Geforce GTX 970 graphics card. A powerful machine whichever way you look at it so im sure a huge difference wont be made

Does anybody know whether the benefits of acceleration will apply much to me? I know utilising my GPUs CUDA processors for rendering in After Effects and Blender makes a very very large difference, i just haven't observed any difference with PDN yet

I tend to work with Effects>Distort allot with canvas sizes around 8000x8000

Thanks all :)

As far as I know, hardware acceleration via Direct2D only means the actual display and maybe some of the layer stuff of the image. Not the actual rendering.

 

Rendering is all 100% CPU to my knowledge. No DirectCompute, CUDA or OpenCL. Unless some very adventurous plugin writer goes nuts.

Paint.NET use Direct2D in hardware mode mostly for blitting tiles in the canvas, and for any UI sitting on top of the canvas. It is noticeably faster with hardware acceleration with something like a GeForce 970, although Zagna is correct that most processing is still done on the CPU.

Put another way, if you were looking to build a new PC or to upgrade an existing PC with the goal of improving Paint.NET's performance, your GPU would probably not be a consideration unless you're using something truly abysmal.

 

CPU, disk, and memory size are much more impactful by orders of magnitude.
