> Not that we're there yet Heiko and Vivian, please try the following version and let me know if this improves anything. If possible, do all tests with the weather tile type 'Test' (that has no randomness in the cloud configuration selection, so it delivers a fairly reproducable situation in terms of cloud count).
http://users.jyu.fi/~trenk/files/advanced_weather_v1.47.tgz I've tested this in the default shading with the ufo in window mode without expensive shaders running so that I got a high framerate. I've seen framerates of 65 fps with max frame delays of order 15 ms (which seems okay so far). Every few seconds there was a prolonged frame of 30 ms (still within my design targets, but suspicious). I've tested the hypothesis that the only loop not running per frame now causes this (the tile management loop) and switched it off - the problem persisted unchanged, so to my ability to test this feature was not caused by any Nasal code running (it might still have to do with Nasal overhead like GC or so, that I couldn't establish). Every 30-40 seconds I had a freak-frame of 150 ms duration coming in. To test what is going on here, I disabled all running Nasal code by clear/end - the problem persisted. To my ability to test, this is also not caused by running Nasal code but by something which I couldn't identify. I've subsequently tested the visual impression of flying with an aircraft rather than the ufo and took the Harrier for a spin through 6/8 cloud cover (one of the low pressure scenarios). It certainly felt smooth to me, although the framerate and frame delay readings were a bit more jittery than with the ufo. So, I'd like to know if that helps you as well and if we're on the right track here. (Even if this works fine, please do not commit yet, I am not 100% sure that I didn't create an instability somewhere). * Thorsten ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
