If Nv2 runs flawlessly on your computer, but NReality lags for no particular reason, (a problem, according to CF, that frequently occurs on PCs with multi-core processors), (I misread, multi-core processors in themselves aren't the issue, but rather the processing power of one of the cores), and you have tried all of the traditional fixes, then creating a projector of the NReality swf using the more current version of flash that Nv2 runs on may help:
Note: This is aimed towards windows users, but I assume there is a similar process for mac and maybe linux?
Note: You may want to back up your .sol, just in case something goes horribly awry.
- Open both your NReality and Nv2 folder(s?) in two(?) separate windows (if applicable... you should be able to see all of NReality's files and Nv2-PC.exe simultaneously)
- Locate the NReality_v6g2.swf (not exe) in your NReality folder, and drag it onto Nv2-PC.exe to open it with that version of Flash (probably 11.1.r102)
- If step 2 was done correctly, NReality should now be running with Nv2's version of flash. (Hopefully N does not appear to be running at an abnormally speed, but that may not matter)
- Click on File and choose the Create Projector... option, and then save the file as whatever you want; just be sure to save it in the same folder as the original NReality!
