Unable to get the Begginer's Racing License Achievement (fps problem)

I'm unable to pass any of the timed challanges (like the accelaration and braking) due to the timer not realising that my game is running at 15 fps at best so even with perfect launch and gear shifts (using clutch) I'm running out of time in about half of the acceleration zone.

Is there a way to fix it other than buying a new pc (that's kind of expensive)?

 

You need at least 20FPS.
Below 20FPS no race with time limit is possible, because your game is not running in real-time.

 

So how can I get 20fps on fps heavy maps like ETK test map without buying a new pc? and couldn't the timer just run in 2x slow motion the same as the whole game?

 

Well, if you are using a PC that is below the minimum requirements, there isn't much that can be done.

Turning everything to the minimum possible, even the resolution are your only solutions if using hardware too slow.

 

ok thanks anyway
