I am experiencing low fps but not always. There seems to be a [s]pattern[/s] co-relation with GPU utilization. GPU utilization drops by around ~50% when running SE and this translates to half fps. But it doesn't happen always. I tried changing power management mode in nvidia control panel -> 3d settings for SE but nothing changed. The GPU throttles down by ~50%. I checked temps and under full load they are ~76C which I think is OK. I think it started happening at some point after a driver update. But I don't want to roll back to an older driver unless I am absolutely sure it is a driver issue. I include SE.log for further investigation. Thanks for any help.

sorry for the zip it wont upload otherwise.
[s]Update on the above issue:
Unfortunately things have deteriorated for me regarding the above issue. Now SE is almost unplayable. I am now getting around ~11-15 fps when orbiting a planet in low orbit and around ~20-25fps in deep space. The GPU usage is now ~11% with max20% spikes while playing SE. When on the main menu it is almost back to normal ~60-65% with fps reaching 60. It doesn't matter if I have ultra settings or low settings: FPS is always around 11. With GPU utilization also around 11%. Things I've tried are included in a separate file because message is too long otherwise.
The only think that remains is uninstalling and reinstalling SE. If this doesn't work, than there is no other option but to format and reinstall OS and everything from scratch.
Any help is greatly appreciated.[/s]
OK I have figured out (probably) the cause of the above GPU behavior: It is reducing its utilization when certain types of addons from the workshop are used and especially in combination. Which addons? Mainly the following:
1. Gaia catalogs (the larger, the worse). 1 Million is the best balance as the author suggests.
2. JPL asteroid catalogs. Two of them. If used combined it is worse
3. Artificial Satellites: Six in total. Again if used combined it is worse.
If all the above are used combined then you get a very lazy GPU that sits at around 11% giving a nice 11 fps..
Now I don't understand why the combination of the above addons makes the GPU to go lazy. I observed task manager in case the CPU is bottlenecking the GPU (or the RAM) but these two don't change dramatically. The CPU utilization doesn't change virtually at all. And the RAM does change but only drastically if the very large GAIA catalogs are selected. The system volume disk (two ssds in RAID0 config) utilization is also dormant. So I don't understand the causing factor for this behaviour. MAybe the program can not handle so many requests from the very large catalogs - who knows.. Anyway I am happy its not appear to be another issue with my hardware or a OS/driver issue

. Sorry to bother..
