4090 stuck on boost

Hello,few days ago i build i new pc with the 13900k and a zotac 4090 aio,works great but i realise that the most fps killere of all is a program,FSLTL…really kill a god 50/55 to 20/25 with the fenix,(all on ultra+4k)but the poi t is that only in some situations the gpu(overclocked by me a little,nothing serious)is stuck on the boost,the max stock of the gpu,in this case 2850mhz…its like wipe out my oc…this happen sometimes and of course only with this games,others it is like a bomb.
I khow that msfs dosnt like oc at all,but i expected an error instead,not a limitation…
IF someone know what can it be,thank you in advance

Hello!

Your topic has been moved into the General Discussion & Community Support category.

The Bug Reporting category is for posting suspected or confirmed bugs in the base sim (no addons / 3rd Party) that other users are able to reproduce without duplicating an existing bug topic. Using the template is required in order to provide valuable information, feedback, and replication steps to our test team.

If you are not sure if your issue is a bug or need further input from the community, please use the General Discussion & Community Support category. If the community can replicate your issue, first search the Bug Reporting category to see if there’s an existing topic. If it already exists, contribute to that report. Duplicate bug reports will be closed.

If you believe it is a new report, then create a new bug topic using the provided topic template.

NOTE: All issues caused by or involving third-party addons/mods should be reported to the third-party developer. Assure that no addons/mods are used when reporting issues in Bug Reports.

It is most likely that your system is heavily CPU bound in the scenario you mention, so the GPU is not running at 100% (because it doesn’t need to) and hence is down clocking with the lighter GPU load, regardless of your overclock settings. This is nothing to worry about and is normal.
