Referring to post #32 above and same equipment and configurations. without OpenGL 7% CPU and 0% GPU with OpenGL running Version 2007 CPU has gone up to 8-8.5% % and Single GPU is approx 70-75%% after a minute or so. Note: The earlier version in post #32 was around 1984 if i recall...maybe sooner Same (8.5% and 75%) for version 2008 (pre-release). What is curious is that the CPU has also gone up with OpenGL running. With some further experimentation....I found that the bulk of the GPU utilization is comping from the displaying of two TPO-Profiles I have in my chartbook. Chart 1 has Day session and Evening Session enables (two profiles per day) Chart 2 has only the day session enabled I minimized Chart 1 that shows two profile periods per day (intraday and overnight periods) and the results with OPENGL running are CPU 3-3.5% and 27-30% GPU I minimized the Chart 1 and Chart 2 (one profile period, no overnight) with OPENGL running and the results are: CPU 2-2.5% and 22-24% GPU - basically no TPO charts running Both TPO profile charts open: CPU 8.5% and 75% GPU Next, I disabled the Evening Session in CHart 1. SO both charts are only day session. and being displayed; CPU 4-4.5% and 30-35% GPU Conclusions: - The TPO profile charts are extremely GPU intensive and a simple TPO profile charts almost doubling the utilization of all other charts in chartbook (approximately 12 charts plus spreadsheet) - TPO profile with just day session (no evening session) while adding a lot of utilization is far more reasonable that also enabling the evening session. Maybe the TPO profile studies could be revisited to understand why the GPU utilization is so high especially with the evening session turned on when using OpenGL? Without the TPO profile charts/studies.....the OPENGL utilization is quite reasonable. Update: after setting for awhile the GPU is now 80-90 %...wonder if there is a leak....related to TPO charts? P.S> I'm using 2 monitors which, with experimentation, have no effect on the GPU utilization in this experiment. also, note that the GPU utilization climbs slowly (a couple of minutes) to that 75% mark after bringing up a chartbook. I have an AMD Ryzen 7 2700x processors and an Nvidia Geforce GTX 1660 Ti graphics card with two large monitors. Date Time Of Last Edit: 2019-11-09 18:00:32
