Performance of the game

Hello! Beam.ng has always run at 60 fps for me at medium settings and dipping into the 40ties when driving fastly, but when i launched the game today it took like 20 minutes to load in to the map (Italy), loading in the car takes around 2-3 minutes and then, when its all ready, i step on the gas and get hit by a massive lag spike taking me to around 5fps and lagging very noticably. Is this a bug caused by a new update or what? I havent researched when a new update dropped but i got the game around the end of June.

My specs -
I have a laptop btw

Nvidia GTX 1050ti
i7-7700HQ @2.80Ghz with integrated graphics
8gb of ram

 

Be sure you're using the dedicated GPU, in your case the GTX 1050Ti, also, check for nvidia drivers updates.
Since we're in summer, the power of components can be more limited due to the higher ambient temperature, please be sure you're not Thermal throttling, by using a monitoring software such as HWMonitor (you can download the portable edition, so you don't have to install it).
Be sure that the graphics settings are not changed by something (it may happen sometimes).
Remember that the Italy map is very resource demanding (it takes 1 and a half minute to load on my main rig), so your pc may not be enough powerful to run the map smoothly, in that case, lower the graphics settings to play at reasonable fps.
