CFT and TN spikes
Hey all, Firstly, I've had this issue for years and I cannot seem to resolve it. Every couple minutes during gameplay I get random CFT and TN spikes (see attached pics) which always screw me up. ...

Here's a vid showing a couple stutters. I have a couple more if required. Most showed a high yellow CPU spike on the in game graphs.. A couple did not however.

elderwarriors , yup absolutely everything disabled.
I watched the video and there's a large CPU spike of what appears to be 345ms.
The next thing to look at is if any of the CPU cores are reaching 100% usage in Windows Task Manager. It line graphs all of the CPU cores which will show if any are hitting 100% usage, which I suspect one of the cores is hitting 100% usage.
To see if any CPU cores are hitting 100% usage in Windows Task Manager.
- Run the game in windowed mode (alt + enter)
- Open Task Manager (alt + ctrl + del)
- Set Task Manager to 'always on top' by clicking option
Now you can play the game and monitor CPU usage per CPU core. If any CPU core hits 100% usage the game will stutter. This is important because it only takes one CPU core hitting 100% usage to cause the game to stutter.
To see CPU usage per core in Windows Task Manager, open the Performance tab, then right-click on the CPU graph and choose "Change graph to > Logical processors".
Thanks for the response!
If a core is spiking, what would be my next step?
If a core is spiking the next step is to figure out what's causing it. App, driver, CPU frequency downclocking.
I would start by watching the CPU frequency in Task Manager to see if it's being downclocked to a lower frequency due to power saving settings.
