Hello! I am interested in the answer to the question regarding Vray RT GPU. Creating a scene, I had to use high-resolution textures in the scene (6000h60002048h2048, etc.). In my two graphics cards for 3 GB of graphics memory and render the image error takes to close vray rt rendering, and memory graphics card fits 3000 GB and abruptly collapses with etoi oshibkoy.Estestvenno no picture no. By using the "resize textures for GPU" even in the format of 2048 is still not render zapuskaetsya.Tolko if I change the setting to 1024, all rendered, but the quality is awful textures when rendering 6000h4000 permits, etc. If anyone encountered this problem and knows the solution, I beg you to help me !? PS I do not want to customize the rendering on the CPU, because the rendering takes forever.

Friends, there is a problem of the following properties. Always render the machine without a video card. Recently, in order to accelerate rendering bought geforce gtx 970. As a naive thought that is to insert the card, and just go faster rendering. But when I started to render it was discovered that in the process of the card is not loaded at all, it is idle. Googling revealed that on the GPU can only be unbiased, which is done through the Vray RT. Trying to do such a thing, I got the error "Could not obtain license (10061)." There are iray, which allows you to use the GPU to render, but I have always worked with the vray, and its not going to change. The question is this: is it possible to somehow adjust the purchased card to work? Or is it besoplezno ... Thanks for the tip!

Hello!

There renderers that use the CPU - CPU renderers, there are used video processor - GPU renderers. Hybrids, which would use both, that is, for example, CPU renderer, used to accelerate more and GPU - yet.

In other words, the card is that it can not be used as an additional accelerator, it can act as a separate module rendering and you have to choose, either to render only the processor or graphics card to render only.

At this point, the functional for the CPU renderererov a significant advantage over those that just-rendered graphics forces.

Thank you, Anton! However, in this case, I do not understand: here you write that for 3dsMax need gaming card. http://renderstuff.com/best-video-card-3dsmax-june-2015-632/ Then it is not clear what exactly is it for? Redner GPU, in fact, flawed. In the viewports, as I understand it, it is necessary only in Realistic mode, which I do not use. Now I think just to pass the video card back to the store, because no benefit from it at all (poluchetsya that just need a PC with a good processor (i7-4790K), more memory and dual-channel mode with it - that's the best iron, which can be bought for habitual money (tens of thousands of rubles).

The card is necessary for a good performance in-viewport, that is, to "quickly spun" ranges when working with a stage, for example, when modeling or "seating" hundreds of trees to render the exterior. Moreover, there is a ceiling capacity of the viewport-engine and after a certain level of performance, the benefits of "super-duper" cool graphics in 3ds Max simply will not. In an article about choosing a video card it only on the viewport-performance, not talking about GPU redneringe speech.

If we talk specifically about your case, my personal opinion, if you're not going to play it in the game, then rent it and take something twice as modest. Or rather Look at the recommendations in the above article. As a result, less buzz, warm and guzzle electricity will be, and the release of the money still buy the RAM, or capacious SSD drive 😉

Thank you, Anton, you really helped. So I did - gtx 970 passed, bought gtx 960 and another 8 GB memory. I used to have stood 8 GB one strap. I noticed that when rendering more than 6 GB was not used. It seemed to me that this is enough, but now there are about 10, and the speed increased significantly. Does this mean that if you insert another 2 strips on 8 (total 32 GB of memory will), it will even speed up the rendering? ps: maybe the speed increased incl due to the fact that the dual-channel mode involved with memory. Planck has been specially bought exactly the same as the first.

I would not want to move away from "videokartnoy" theme of this discussion, therefore, in a nutshell, a significant impact is to speed the rendering memory is not provided, but no doubt increasing its number increased overall responsiveness of the system and the more positive impact inclusion of dual-channel mode with pair number strips. So I can only congratulate you that you have found the strength to look into the matter. Many trideshniki irrational by iron, rather than mend as you do yourself (ouch) itself is better, on the contrary - by all means justify their irrational purchase, not wanting to recognize his same mistake as myself harm. That's the way great video on the subject: GTX 670 prices between $ 310 and above (depending on the manufacturer, performance, store). GTX 780 prices of $ 450 and above (depending on the manufacturer, performance, store). That is the difference in the price of $ 100 +, and the difference in the speed of the viewport is almost there. One may look into the FPS counter, but the real difference is perceptible in the viewport is not, or at least, it is a very formal level chicanery. My personal opinion - the difference of $ 100 is not worth it, even if they are. Where profitable to spend on more powerful processor or memory, as did you.
