Temat: no to ja tez tu napisze
i tak większość operacji wykonuje nasz CPU, chyba ze mamy jakaś specjalna kartę dedykowana pod PS.
a to co znalazłem na sieci odnośnie tuningu photoshopa. (napisał to koleś z teamu photoshopa)
The tips:
1) If you only have one hard drive and work with large files, consider getting at least a second hard drive and set that to be your scratch drive. If you can pack three drives into your machine, I would recommend one with your system and Photoshop folders and the other two drive RAIDed together and make that your scratch disk. RAIDing the two drives lets the OS treat them as one large drive but with almost half the access time (double the speed). Very nice.
2) Multicore or mutliprocessor machines. When Photoshop is working with images that are in memory, it will divide up the tasks across as many processors as you have. There is a curve associated with the number of processors and the speed up that you see, because past a certain point, overhead of communication takes more and more of your speed. So, with each processor you add, it will be faster, it is just a matter of how much faster per processor. Two processors is a nice area to be in, four if you can afford it. Around eight or more, I do not have enough experience with that configuration to comment.
3) Get the fastest memory and memory bandwidth motherboard that you can. Many of the Photoshop operations are memory bandwidth bound. This is very true with multiple processors, since each processor needs a certain amount of memory bandwidth to move image data around for processing. Also the more memory you get, the better. Photoshop will use up to 2 Gig of memory (or 3 Gig depending on the OS and machine), but anything beyond that amount, the OS uses for either other applications or caching. So, if you are switching applications a lot or working with a lot of image data, there is a big win for more memory.
4) GPU. For now, this doesn't matter that much. A recent video card is good, GPU doesn't really matter. True, GPUs matter more and more, and many applications use GPUs, so having one might help you in the future or it might not, but it really will not do you any good right now. I'd say wait until you know you need one, because by then, the performance per price will be much better. Until then, a video card with fast 2-d will be the biggest win in this area.
We try to make Photoshop do the most the hardware that you have. So, the better the hardware, the better the performance, with the exception of GPU.
