Hello!Strangely enough, but most of the misunderstandings of such a plan, only misunderstandings.Their reason is trivial. To determine the degree of CPU or RAM usage, users use all sorts of gauges, third-party programs, etc., which simply do not objectively monitor system resources. Even if the percentage is loaded by 100% and the RAM is completely clogged, such programs can erroneously report not fully loading resources.If we talk about the real underload of the processor, then the main reason for this phenomenon is also very trivial. V-Ray simply does not have enough RAM to render and it uses swap. In turn, during the loading / unloading of data, not in fast RAM, but on a slow hard drive, the processor is idle. For sure, if you look at the indicator of the hard drive, then in the situation described by you, it most likely flashes without ceasing. This eloquently testifies to the problem of shortage of operative memory.Given that you have a laptop, then, even the performance models based on the Intel Core i7-2670QM (2.2 GHz) processor, rarely have more than 4 - 6 GB of RAM. That, in general, not so much. But, if you still have an expensive copy with 8 GB of RAM, it is also hardly possible to call it a "good stock" in the "heavy" scene.In addition, you should definitely make sure that you are using 64 bit version of 3ds Max. Otherwise, no matter how much RAM is installed in your laptop, more than 3.2 GB per process (in your case, rendering) will not be used.A more serious problem is possible. The matter is that some manufacturers of laptops install special energy-saving software, the purpose of which is to reduce the power consumption. Of course, by reducing the load of the GPU and CPU. It can also be the cause of CPU underload on resource-intensive tasks.You should make sure that you do not have such "branded" utilities on your laptop.In a more radical case, such an energy-saving algorithm can be "sewn up" at the BIOS level of the laptop's motherboard. In this case, you can turn it off in the BIOS settings, or you can not.Apparently, Intel® Core ™ i7-2670QM - uses Hyper-Threading, that is, it breaks each physical core into two logical ones. It is possible that this is also a formal cause of underloading. Go into the BIOS and cut down the HT. Perhaps this will solve the problem😉In any case, one way or another, you should understand that the laptop is far from the best solution for professional rendering. Therefore, if this is really a real problem, and not a banal resource monitoring error, it is quite possible that you will not be able to solve it.But you are always mobile😁
No, we have not found him literally reproach. Just your message looked very rough and containing "unproven conjecture in the affirmative and exclamatory form."
You have not commented on it, on what basis are you sure 100% fidelity resource monitoring. I not tried to disable the HT, and check for other possible causes of underutilization described in the answer to a given question thee.
In addition, so far it is not clear at what stage you are rendering underutilization. In step load geometry GI calculation step or already during the final rendering. The first two stages can be easily underload percent to 100% due to the specifics of their algorithms. And in the end, he did not provide any information about the stage itself and its settings. In particular, on the type of reykastera and available in the proxy scene van, and other important details.
However, your initial question is quite pertinent in this section the discussion. We like it and just so your koment was correct, and not removed for violating the above requirement.
If you really want to understand the problem that is described thee in the beginning, then you should try all the options that I'm advised. Then report the results to us, or anyone who has encountered and found the answer to this question could help you😉
Hello!Honestly, it's not clear where the system writes what 4 is available, and how you determine what is used 2. In any case, you should get to know what SLI is. Then, you will find out that video memory does not stack. This is in principle not logical, since SLI is just a division of the image into portions and rendering these portions in different video cards, just as the distribution rendering does. For example, the frame is divided (conditionally) in half, into two half-frames. Then, one half-frame is sent to render one video card, and the other half-frame, another video card. After that, both video cards calculate their part of the frame and, an additional video card, transmits the calculated half-frame to the main video card. The one to which the monitor is connected. Having received a half-frame from an additional video card, the main folds it with its half-frame and forms a full frame, immediately sending it to the monitor. But not as a single whole frame, it is calculated at once by two GPUs: By the way, as far as I know (I can and make mistakes), it is because of this need to return parts of the frame for assembling it into a single frame, the SLI system is not scaled proportionally. That is, installing two video cards in a system that support SLI (dividing one frame into parts) of the application does not work twice as fast. As a rule, they work only on 20% -30% more productive than a single video card. Only in very rare cases, the increase is up to 50%. For example, in video cards with two GPUs on the board, which do not need to exchange data via the system bus or SLI bridge.
Good afternoon! The story is long, I ask you to finish reading, I tried to describe in detail)The computer at me:I7 CPU 920 @ 2.67 GhHz 2.66GHzMemory (RAM) 6GB (4GB available)The video card now costs Nvidia GF GTX 560 1GB / 26b N560GTX M2D1GD5 VX64-bit Windows 7 is the maximum3d max 2013 installedThe computer is powerful enough and works slowly, after rendering is especially difficult.At the beginning of the working day it still works fine, but in the late afternoon it's really a brake ...It started all month ago, my own video card burned down. Let's go buy a new one. We took Radeon, the numbers do not remember 1GB anymore, but it did not fit, after a few days of use it started to cut down, a black screen and intermittent hiccups, well, it's not so important, because Cam factory marriage. Exchanged for Nvidia GF GTX 560, and like everything is ok, it works well. Comp of course, everything also gets tired by the evening and after 10 minutes the render seems to come to life🙂 It's especially hard for him when you switch from one program to another. For example, my work is always included in parallel 3d max and Corel x5, and so in the transition from one program to another (one at this time collapsed) the computer brakes heavily. (Although it happens that in the morning only 2 programs work without rendering, Queues open both completely calmly), but after work in the browser (google chrome) in general trouble, unfold the program and wait until it hangs up: buzzing loudly, first around the perimeter of the badges will appear, then the middle opens with difficulty.Well, that's my main problem: three days ago a black screen appears during the render, the computer did not turn off. On the monitor (I have Samsung SyncMaster B2230) only the lower and only blue light is blinking. I really thought that again the video card, but after the reboot everything gets better and I continue to work. The next day is about the same, the black screen lights up, only on the monitor runs the sign "check the signal. cable". I change the cable to the same from the old computer. Again I turn on the computer, and again everything works. The situation is repeated 3 times (the cable returned home). I thought that there could be a problem in the monitor.I went and bought a HD cable. I'm working. At the end of the working day - black screen. The signs "check the signal. Cable "is not. Comp almost silent, but turned on. Suddenly it starts to sound very strange and loud. I look (the benefit of the lid is open) on the CPU fan rotates with a crazy force. I turn off the computer from the button.Enable - everything works. I conclude that the problem is still with the video card.Logically I can assume that this is an incompatibility of a video card with something else, maybe with a motherboard.Please advise what I do, contact the warranty service with a video card or change something from iron?Advise how to be. The computer is powerful, and it does not work at full strength why that. At that time, in general, pentium 4 stood and quietly experienced parallel work in several programs. Of course, then the max was 8 and 13, and the renderers are not solid, but still ...This brother bought a computer 2 years ago, he worked gorgeously always, fled. And I ...When the computer slows the CPU load, it reaches 10%, but mostly 1-3%. RAM (RAM) is over-scale above 54%. Once it came out yes 98 (but it's in my opinion with that not suitable video card)In general, as she could have described, you give all such practical advice, there is only one hope for you. 😉 Who just did not ask only hands are bred 🙄
