Major FPS Drop After Enabling External Simple ESP Hack

I was getting around 150 fps yesterday using the same hack. But when i tried today im fps is now 50.
The moment i turn it off it goes back to 150 fps. I noticed a change in the colour of the ESP Boxes overlay which was Red and now it have become a Darker Red. Tried Lowering the ingame settings. made no difference

If its the Simple ESP Forta_Pt than you want to stop using it asap! That shit is detected!

If its not though, its probably because most hacks are demanding on certian PCs and that there was an update recently. These are all likely guesses
