Razer Cortex Boost tanks frame rate

The most recent update to Razer Cortex has caused my frame rate in Kena Bridge of Souls to tank to single digit levels.  It does not seem to be affecting any other game that I play (for example Mechwarrior 5 still has the normal high frame rate).  But there is a very definite correlation between Cortex Boost and Kena.  When I turn off Boost the frame rate is normal, when I turn it on it takes 2 minutes just to start the game, and I estimate the frame rate to be about 1-5 fps when I normally clear 60+ easily.

I am running an i7-12700KF, 32GB RAM, Windows 11, and an NVIDIA RTX 3080 with the latest drivers (as of 10/31/23)

Boost has the following settings: Enable CPU Core, Disable CPU sleep mode, Enable game power solutions, clear clipboard, clean RAM, Windows Key, Sticky Keys, Disable Cortana, Disable background apps, disable telemetry, disable report problem.

I have a work around by disabling boost, but it is very irritating and took me 3 days to figure out that it was your product that was causing the problem.  Please have your people look into this as I do like the functionality that Cortex Boost supplies.  Thank you.

As a Razer user myself, I understand how frustrating this situation is for you. But not to worry, I will be here assisting you to resolve this issue.


Please follow the steps below to troubleshoot on your side:

We’ll be looking forward to your reply soon. Thank you for being patient. 



Thank you for the response.  Deselecting ‘Enable CPU core’ seems to have solved the problem.  I was able to start the game and load a save in the normal amount of time.

If I may make a recommendation, if technically feasible, the addition of user definable game specific profiles would be a nice feature in the future.  The main reason I say this is right now to solve a problem with one game I have to disable a functionality for all my games. (or remember to turn it off before I run Kena and turn it back on afterwards)  Theoretically with the right combinations of games you could have to disable so many features that boost is essentially useless.  Your application seems to be intelligent enough that it recognizes game and non-game applications.  It doesn’t seem like it would be that hard to allow a user to specify a particular executable attach it to a profile, and have specific features for that profile.  This could also allow you to ship ‘default’ optimized profiles for games that have known issues with one or more boost features.

Anyway my 2 cents worth.  Thank you for the assistance.
