<div dir="ltr">After some more diagnostics we found that the graphics card memory was full during the large intervals. As we did not manage to monitor the graphics card memory usage in normal operation, it is not entirely certain that this is the cause, however since the normal memory was slowly being filled during the large intervals this seems to be the main cause. I am wondering if there are typical settings that we can modify in order to reduce the graphics card memory footprint? If not, we should consider updating our hardware I guess.<br>

<div dir="ltr"><div><div><div>Just a small update:<br><br></div>I had in fact originally not used the offscreen rendering, so yesterday I started the animation with offscreen rendering checked, cache geometry on with 1MB of cache limit. The weird thing is that I started creating the animation around 9.30 am yesterday morning and it than took until 3 am this morning before 4 frames were created (2 large 8 hour intervals). After that the performance was ok, with approximately 9 frames per ten minutes on average. I will start one animation without caching just to complete the 4 different settings that are possible with these two options checked/unchecked.<br>
<br></div>Quality of the frames is not affected it seems, at least not visibly when viewing the animation, so that is good.<span class="HOEnZb"><font color="#888888"><br><br></font></span></div><span class="HOEnZb"><font color="#888888">Tom<br>

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div>> I'd like to find out why the offscreen is so much slower - does the offscreen redering session get created and destroyed on every frame. When generating 2000frames or so it can make a big difference.<br>
<br>
</div>I just verified that it doesn't do that i.e. doesn't create and<br>
destroy the context on every frame when saving out animations.<br>
