please may I ask whether developers or anyone else have access to Intel NUC8i7HVK? I have been fighting rather strange behavior of GPU on this nuc for several months. I can’t seem to solve this and it somehow seems to me like issue related to Touchdesigner (however I am not sure about that).
GPU used in this nuc is Radeon RX Vega M GH. It works like expected, but when it comes to using Touchdesigner, it does not perform very well. Problem is that GPU Core Clock is fluctuating when using Touchdesigner and therefore it does not have enough power to keep steady framerate. It is dropping frames even though it does have enough power to run just fine.
Touchdesigner sometimes makes it utilize full Core Clock speed (1190MHz as it should) and then it works perfect. However getting to the state when it runs properly is like being defined by non-deterministic random (sice it happens only sometimes and is not related to anything I could possibly think of). When this happens, it could run whole days just right - without ever dropping single frame. Once restarted, it gets back to “bad” behavior - and constantly changes Core Clock when using Touchdesigner - therefore dropping frames.
I have been testing this with 3 different Intel NUC8i7HVK and all of them behaved the same. During last year I have gone trough multiple versions of BIOS and its configurations, multiple versions of GPU drivers and their configurations, several Windows and Touchdesigner updates, but none of them made a difference.
Other graphics related software makes this GPU utilize full Core Clock speed without any issue. For example when running UNIGINE benchmarks it works just fine every time - using 1190Mhz and therefore getting the most out of it.
Please does anyone know what might cause behavior? Thanks in advance.
I am currently using Windows 10 1903, BIOS 0058, AMD Radeon 18.12.2, Touchdesigner 2019.18580. I am attaching screenshot from GPU-Z showing Core Clock when runnging Touchdesigner in perform mode.
