Stereo Tool

i have stereo tool on every channel and it eats so much memory i have 32 gb memory in my pc and already reduces the audio quality on resource usage to a minimum. and used the present optimized for latency. but i have still huge lags. any other settings what i can use to solve this massive latency problems. my latency is 260.50 ms.

i have only 2 things on stereo tool active. but also if i disable it. the vst generell eats so much memory. i use fl studio

is there any different between fl64 and normal fl? or i need a other vst version? maby vst3? i have only the normal vst version. without suporting 64bit

the buffersize is already on fl asio on 2k more i cant add.
