If tons of people are having problems on R15, we may be able to ask DICE if we can revert to R14. They'll be checking out the data early Thursday morning (which is their normal business day) and providing guidance.
The crashing is ridiculous with R15.
I have one server that is running R14 and it hasn't crashed since the Battlelog/B2K release debacle. My other two servers that are running on R15 crash constantly and especially as the in-game player amount increases.
It seems to be a common issue across the board:http://forums.electronicarts.co.uk/batt ... e-r15.html
