I just did a test with 64Bit + OC The CPU stays at 4480MHz per core most of the time with about 50°C average temps. Compared to the 32Bit version there is a timepoint where the 32 bit gets faster than the 64.. that might be because, there is a stage where the hole thing gets unstable and i didnt dispatch it when i did the 64 bit test so i had to get the rocket back to a straight up movement. (seems like the staging needs some adjustments with "real-time" calculations ) Same URL as before but here: https://www.dropbox.com/sh/1qxb8k7td...UZFZsRfTxLMU6a Comparison 32/64-Bit (I also uploaded the pic to my dropbox folder): EDIT: Okay the picture doesn't seem to work, or/and I'm just too dumb to get it working.. Anyway I could further increase clock speed to 4.6GHz per core! Now i hardly get below 30 fps (only once in the test with 29 fps). I already uploaded the file (+ 4.5GHz comparison graphics) to my above mentioned Dropbox folder. (it's the .xlsx file)
