claudiuionescu Posted June 22, 2015 Share Posted June 22, 2015 Hi there! I'm new to 3ds max and i have some problems... I have a scene with 6 mils. polys / verts. When I open 3ds(2015) with this scene everythings ok - more than 60 fps. After ~30 minutes things goes crazy and the fps are getting low - less than 20 fps / and when I rotate the viewport ( perspective view - shaded ) the objects becomes wireframe for a few seconds. Can anyone tell me what's the problem / a solution? PC Specs CPU -4930k GPU - 780 Ti Dual Classified 32 GB RAM SSD 256 GB PS - excuse my language Link to comment Share on other sites More sharing options...
Josef Wienerroither Posted June 23, 2015 Share Posted June 23, 2015 could be anything , without the scene being posted such things are hard to catch, if the cause lies in the scene But you might take a look at your task managers memory consumption for Max, i doubt that it hits your 32GB limit, but maybe it does because of some leak. And check wether your CPU is at 100% on some of it's cores when the slowdown happens Link to comment Share on other sites More sharing options...
claudiuionescu Posted June 23, 2015 Author Share Posted June 23, 2015 I've tried the scene on other PC ( 5280k / GTX 970 / 16 GB RAM / 128 GB SSD ) and everything works fine and clear. It may be a system error or something... I've checked task manager and only 8 GB RAM / 20% of CPU uses... Link to comment Share on other sites More sharing options...
Scott Schroeder Posted June 23, 2015 Share Posted June 23, 2015 What are your GPU and CPU temps like after thirty minutes? Perhaps you are having heat, or excessive heat build up in the case, issues? Link to comment Share on other sites More sharing options...
Josef Wienerroither Posted June 24, 2015 Share Posted June 24, 2015 (edited) ...20% of CPU uses... Well - that means that one core might be fully clogged at 100% on your six core CPU. If this is Max using that CPU time with just the scene loaded without you doing anything this may cause a heat issue, as Scott mentioned ). For a test you might turn off progressive refinement of the viewport ( Max improves viewport rendering quality over time ). The setting is in Viewport Configuration->Display Performance->Improve quality progressively ). Check the CPU usage of Max and temperatures again after that...

claudiuionescu Posted June 24, 2015 Author Share Posted June 24, 2015 CPU - ~ 36/38 °C GPU - ~ 48 °C I don't have any problems with the heat.. Link to comment Share on other sites More sharing options...

I tried with - Improve quality progressively and nothing happend. Thanks for answer anyway Link to comment Share on other sites More sharing options...
