Im runnings 3 obs instance as nvence cant suppport more and everything ok. But sometimes obs just put upload speed to 0 and when i try to w8 when dynamic bitrate will fix this its just nothing happens.then i try to change upload speed manually and obs just crashes. This can be fixed somehow or i need use another streaming software?

Start by using Windows Update to update Windows 10 to 2004 or 20H2/09 if available. Your version hasn't been supported in almost 3 years.

They did a sneak-update to the software in a driver update within the last couple of months, raising the concurrent session limit on consumer cards to 3. It's purely a software limitation; people put out patched drivers with the concurrent limit entirely removed.

This is not Only a Software Limit, its a "limit" related to the Resources and the Know of the user of the limitations.
Related to the "think" that nvenc have 0 affect of the card. That only is true if nvenc encode the framebuffer.

The patch for remove the limit to open it to the Pro card level limit, is only work problem free in special conditions on consumer cards related to the physical limits. in a default use way of OBS with a Quality Output 2 encode and above works "only" without additional loads or very low workload.
So to tell 3 or more is default working is totaly wrong, its related to the workload.

And related to the posted log, there is limited to 2 not by software driver or chip, Simple by workload
