Playback issues / High CPU usage when using large soundfont (sf2) on laptop
MuseScore 2.0 beta 2
Using SGM-v2.01.sf2 SoundFont.
On desktop (Intel Core i5-2400 Quad-Core 4 threads) playback is smooth, everything is fine.
On laptop (Intel Core i5-4200U Dual-Core HT 4 threads) playback stutters when more than 3 notes are playing at the same time. The CPU usage rises to 19-25% which maxes out one thread on the CPU.
Memory usage is not an issue since the SoundFont is 250MB and there is plenty of free memory.
Editing the soundfont in Polyphone and removing all non-GM instruments seems to have fixed it but the sf2 file size has not decreased by much
