I recently opened a thread about dkcr having a little bit of lag in the opening cutscene. So I went looking around the net and found out that the IOS's make the difference on how fast the HDD gets readen. I tried out revision 20 and the new revision 21 with: IOS 248: 58 IOS 249: 56 IOS 250: 57 but they didn't solve the problem. All 3 of them had a little bit of lag though one of them had the slightest. I felt like I was close to my goal but I don't feel like connecting and reconnecting the cable again and again. I only have 1 lan cable and no WIFI. So yeah, what's the best IOS revision? Thanks in advance guys. Edit: Maybe it's better to ask if you have the same problem or not, and if not which revision you use.
