Ministry Basement Lag

Just hopped on the newest CTE to try out the Ministry map.

Got pretty solid 50~60 fps on the surface level.

But as soon as I ventured into the basement parking lot, the fps tanks, reaching as low as 10 fps.

No idea what is causing this; could it be a map problem? Hoping for a reply ASAP.

Thanks in advance.

Yeah I'm having the same problem. it seems to be pretty common for lag spikes to occur in the underground level. Maybe it's the lighting assets and shadows being too intense? Hoping for a fast fix.
