Are there any downsides to enabling Message Signaled Interrupts for NVIDIA GPUs?

[Divzed]

Does enabling it increase CPU temps? I read such statements but I'm not sure if they are true.
Also is there a possibility to get worse DPC latency and stability with MSI enabled compared to standard legacy Line Based interrupts? (sutters/hiccups/audio dropouts/frame skipping)
As this guy stated degraded performance on 4080 with MSI enabled, but is this opinion trustworthy tho?

Here once again degraded performance with MSI enabled or placebo? https://forums.guru3d.com/threads/n...oad-and-discussion.447454/page-8#post-6123961

How to increase FPS, lower input latency on ANY GPU with ONE setting

complain about degraded performance when enabling MSI mode, ranging from Maxwell to Ada Lovelace GPUs? Why is that happening?
NVIDIA driver enables Message Signaled Interrupts by default only for Quadro, RTX 3000/4000 GPUs (not all configs?), but anything older below that is still set to default legacy Line Based Interrupts on desktop GPUs (Maxwell, Pascal, Turing...)
Most laptops with mobile NVIDIA GPUs are exception for some reason and they have MSI enabled by default.

Are most of you running GPUs in legacy Line Based Interrupts or Message Signaled Interrupts mode?
