Huge Lag Spikes on Spawns

[Naeblis]

I am experiencing huge lag spike on spawning in legendary or hell runs that usually all but completely freeze me. Before the latest enhanced update this was not happening.

Changed MaxMemoryUsage to equal 32.

Play the game in resolution 1600x1200 60Hz

I have installed the latest enhanced update and this is what I am using:

Sony Vaio VGN-A600P
Processor: Intel Pentium M 2.13GHz
Memory: 2048MB
Display: ATI Mobility Radeon X600
Memory: 256MB
Mode: 1920 x 1200 (16bit)(60Hz)

Please tell if anything other info is needed. Hoping for advice on how to troubleshoot this problem.
