Hi, I am using Win 7 64bit (SP1). And I am running SparkLE in Live 8.3. Version 1.6.1 of Spark only used about 5-8 % of CPU, but now its constant at 20%, even when not playing any other instrument and samples from Spark. Some kit, with long samples consumes even more, up to 50%. I will find out which kit this was later.
PS. Will also add my Desktop specs.
Chers.
