+1 for turning on Low Latency Mode (4070ti Super)
Interesting enough I was running the iGPU on the 14700k for about 2 weeks as this was a new build and was waiting on the Nvidia to come out/ship. Did not have the issue until I popped in the dedicated card.
I did notice a lot of forums made it seem like the defaults were to be set to "on", though the Nvidia dashboard has the default to "off". Maybe it's AMD who set's the default to on for their version.
An observation I had after turning on the mode, the CPU likes to keep at least one core in boost ~5.4Ghz, whereas before it would rest way down ~1.3Ghz at times. Utilization appears to be the same and temps haven't gone up. Then again, I have an oversized cooler on it and don't overclock so my system may not be a good gauge on any temp increases.
