Back in the early days of 1.1 & 1.2 I had crashes both CTD & System crashes. I have a few post on subsim ranting about the sim sucks here or there. I originally had 1 GB ram with no crashes but kind of slow. I then installed two more one GB sticks RAM and wow, game speed up ( for awhile

) then CTD,CTD. Found out I had the wrong RAM. Purchased the
correct one GB Sticks of ram and to this day approximately 115 hours of real life game play later I have
never had a CTD or system crash and SH4 has never ran better. I run "PULL DOWN PACIFIC MAP for SH4 for Patch V1.3 REVISION A" by CAPTAIN COX and a couple more fixes typed in.
So I believe if your computer has a problem with SH4 1.3 it is
not the fault of stock SH4.
It's easy to blame the DEVs (

) but this is not their fault.
And NO the disc is not needed period for 1.3 except to keep the disc jewel case filled maybe.
I have never had the "fade" or bug eye problem. Just to many people whom are
not having CTD's nor buggy eyes for this to be a SH4 problem!
Kind of like putting the wrong type gas in you car and you wonder why it won't run right. Oh right, blame the auto mfg.
