FPS Drops with Time

Hi, when I start the game and do 1st race the fps is normal but I noticed after race or two the fps goes down.
I tested using a replay, when I start the game fresh it shows around 50 but after a that it drops down to around 30.
Even during the menu the fps drops and then I get stutter.
I would like to know why and fix this problem if it’s on my side. So far I’m loving the game very much and I am a pc simracer for many many years.

I run the game on high settings with following pc specs:
i7 920 @ 3.5Ghz
8 GB RAM
AMD R9 280X 3GB
Windows 10 updated

please post your dxdiag info file for full system info. …(how to)

I just want to add that lowering the graphical settings does not help, and overclocking the CPU even more does not help either, same result.

  1. Update your GPU driver at least to the 16.5.1 version with official Apex support
    http://support.amd.com/en-us/kb-articles/Pages/AMD-Radeon-Software-Crimson-Edition-16.5.1.aspx

  2. Maybe you can change the display settings of your TV to 60Hz

  3. After that you should check with a monitoring tool if your CPU or GPU gets (still) overloaded.

Good luck.
