So I start to play aoe2 conqueror on voobly.

When i play in my original aoe2 folder and file, FPS is real good, somewhere around 600+.

However if i play through voobly, which is from a copied folder that voobly did apply some change to (idk, add patch or st), FPS suddenly drop to mid 50 and lag constantly. I note that when lag, FPS suddenly drop to 0-5.

Can someone help on this ???
