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!
And that's it! Hopefully, the next time you open the newly created version of NReality (the one with the red square flash icon), it will run. it will run without the lag that plagued NReality before!
