Just tried lately to use Reaperx64 bit under my System that is running Win 7 x64 bit as well after using Reaper x32 bit (stable like hell of course) and decided to jump give Reaper x64 bit a try and see how the project will handle and how working in x64 bit would come and take big advantage of my RAM system and tkae off the heavy loads that sometimes when you're running x32 bit software can experience and at the beginning it felt nice but when I start playing back etc.. i started noticing "lag time" when I hit play and when I hit stop always that kind of delay lag, like when I hit PLAY, there is a little few (long second) before reaper starts playing etc..
Thats what brought me to start this thread here:

And long story short, I went back and Disable many Services (because I noticed that when I start my computer alone without opening any software, there was 2.50 gig of ram that where used and thats not really normal)and after disabling many services to start at Windows start, now I have 1.5gig when Win is loaded. Which is acceptable.
And then I thought that would help Reaper x64 and my project and to my susrprise when I loaded the Project under reaper x64, it was worst the "lag"time.
Guess what? I went and load up the same project back to Reaper x32 bit and was working FLAWLESS, without any problem no lag nada and on top of that I was able to ago and ADD UP more plugins to finish my project MIX. and Its a heavy project as you can see in the Performance Screenshot there. I have quite a number of plugins load up!!
Thats my experience with first try working with x64 bit DAW in a very big project and "deception" but I want to investigate more because it shouldn't be this way right?
Voila
