3ds max 2013 and gpu clock speed bug?

[orenvfx]

hi

while im testing between 3ds max 2011 and 3ds max 2013 i found some Interesting things.

 

all the testing is on regular directx3d driver mode. not on nitrous realistic mode! tested on 2 system.

 

open 3d max 2011 do not do nothing. and when i look the gpu clock speed rise to 700 and go back to 50 mhz because i dont do nothing and its normal and ok.

 

now, i close 3ds max 2011 and run the new 3ds max 2013 and look the gpu clock speed and its show 700 mhz end stuck on 700 mhz As long as 3ds max 2013 work Causing the video card heat up and warm up to very high temp.

all the tests is on empty scene and with directx3d mode. this resoult is the same with all the dirvers mode even with OPENGL mode.

 

tested with various software like maya, c4d , modo, none of them make this thing.

 

any Ideas why? its a bug that aoutodesk need to know?

please dont delete this post because this is important to People who want to keep in safe her gpu card.

 

my system:

i7 890

 

gpu gtx 460 2 gb

 

12 gb memory

The issue is resolved!!!

 

the over heating and clock speed with max 2013 is resolved!

the cuda option in the gpu controller, if you disable it the temperature and the clock speed is back to normal and cool with max 2013!!

True you fixed it. However, now you just disabled one of the more powerful options of your video card. You might as well go out and buy a cheap $50 dollar card now or use your integrated graphics on your mother board.

 

How does Max respond with CUDA disabled? What are your frame rates like in your average scene? Whats the balance between a semi-issue of overheating (you are well under your limit for you card) and losing power to display and render scenes?

 

My card has CUDA enabled and I don't ever see a temp increase.

[Scott Schroeder]

To add to my previous post. For the second time I'll ask this again. What are your temps like with Max using an average scene?

 

Forget about testing max with an empty scene! When do you ever use max with a blank scene? They have changed things around in max 2013, what was explained to you in you Area thread, and with a blank scene Max may not know what to do. So it just ramps up your GPU.

 

Test this with a normal scene and report back.

hi scott

let me explain something.

the only problem with cuda and 3ds max 2013 with my gtx 460 is that when cuda option is enabled and i lanch 3ds max 2013 the mhz clock speed of gpu is totally stuck on 700 mhz and keep warm gpu with no action or move and becose this stuck "bug" the gpu get 70 - 80 c with no background action! my temp of the room is around 30 c.

now for the good part, i installed 3ds max 2012 who use cuda too, and guess what? the mhz speed clock is normal! when you dont do any modeling or pan or zoom and its 50 mhz and fine and keep the temp around 40- 50c . so .. autodesk?? did you need to fix somthing?? hello?

As it was explained to you in your Area post. Max 2013 has a totally new GPU picking program. You will experience different results from max 2012 to 2013. From what I understand, 2013 will pick the GPU more than the CPU for graphics processing if it can. Which, with CUDA, it will since it's far faster than the CPU. You are now relying more on your GPU than your CPU, even more than in Max 2012. You are not comparing.. apples to apples here since 2013 has gotten a major overhaul.

 

As I've asked several times, how does Max 2013 respond with CUDA being off? This is to build a knowledge base for those who may experience higher temps, not melting temps, but want to control the heat. Does turning CUDA off affect your viewport navigation speed? Does it affect your rendering speed? How does your scene react in shaded or wireframe?

 

You may have solved your heat, but you might be opening up a can of worms with viewport issues. You paid for a graphics card with CUDA on it, now you don't use it. It makes no sense and you are at least 30c under your critical temp for your card. Is it really worth the savings? What about purchasing a cooler for your card? They make ~$20 extra coolers for your GPU if you have a poorly placed graphics card. Mine blasts the heat exhaust into the bottom of my case, so I had to place an extra fan to help push that heat out of my case. Now even in iRay or VrayRT my card rarely gets above 45-50c.

 

You've posted this in at least 6 different forums and pretty much everyone is telling you that your temp is close to normal. Besides, 30c (86f) in your room? Turn on your AC or open a window. That's half of your overheating problem right there. You are operating your computer in an oven. Take your case cover off, does your GPU temp go down? I'm almost betting my entire stock that it's not just Max and it's a cooling issue with your case. Max is simply using more of your GPU, which in turn is blasting heat into your case and you can't remove it. And more heat means higher GPU temp. Again, do not compare this to 2012 since 2012 used more of your CPU than your GPU.

 

If your temp is that much of a concern, why use 2013? Do you absolutely need to use 2013? Why not just use 2012 instead and keep your temp cool? Wait until 2013 gets a patch or Nvidia updates something. Use your EVGA to ramp up your fan to help cool your card as well.

scott you are the king! i want to thank you for the impressive answer!!

Just to chime in here:

Max 2013 does NOT use CUDA for viewport stuff. If you see problems while cuda is enabled it most likely is a bug in Max or in the specific nvidia driver version.

Again: viewports ( D3D & Nitrous) per se in Max 2013 DO NOT use CUDA - only iRay is using CUDA. Even MassFX ( which is based on PhysX - which supports CUDA ) is not using CUDA right now ( according to my info ).

BTW: Max 2013 PU2 (product update) is right arround the corner, and as i can remember a similar discussion/problem being discussed previously, there's the chance that this specific problem is fixed.

No guarantees of course....

after install service update no 2 the problem is still there! autodesk not fix there mhz gpu stuck bug!
