Lagging in Campaigns/Skirmish Frequently

I have a reasonable laptop on which I play aoe2de. It is Acer Nitro 5-AN515-43: AMD Ryzen 3550H 2100 mHZ 4 cores processor, NVIDIA GTX 1650 4 GB graphics card, 16 GB RAM. But whenever I play campaigns the game stutters almost after every 2 3 mins. It stutters even in skirmish but not this frequently. My graphics settings are optimal as recommended by GeForce Experience.
The performance test gives me a score of 1150-1160. The only reason for the lag I can think of is that maybe it is because of the cpu’s temperature while playing which stays between 87-95 degrees celntigrade. If it’s not, any insight is appreciated. Help please. Thanks
