ONE FRAME

If anyone is having issues with stuttering or jittery movement while they have bothV-sync and Multicore Rendering =(Such as described in this thread I have found the fix is to. For example, if you run 60hz like most people, you would limit it to 59. People running 120 would set it to 119. etc. etc.I used a program called MSI On Screen Display Server to limit the framerate. It is included with MSI Afterburner. It works for both ATI/AMD and nVIDIA cards.If you're technically savvy enough and feeling up to it,1. DOWNLOAD MSI Afterburner and install it (two .exes are included in the .zip, but just run "MSIAfterburnerSetup230.exe" and ignore the other one) anywhere you like. You won't be using Afterburner, but instead OSDS which gets installed along with Afterburner.2. Launch OSDS. You will find it inside the "MSI Afterburner" folder in your start menu program folder. It is titled as-- Again,than "MSI Afterburner".unless you just want to. But please see the note above.3. The program will appear as an airplane icon with a littlenumber that displays your current refresh rate ("60" for most people) in your system tray. Click it to open the program settings.4. Click the + plus button that is in the bottom left corner, next to the trash bin icon.5. Find and add ns2.exe (normally in Steam/steamapps/common/natural selection 2/ns2.exe). It should now appear in the list.6. Make sure "ns2.exe" is highlighted and then click the wrench icon in the upper right corner to enter setup.7. Change "Framerate limit" to. For most people this will be 59. Click OK.8. OSDS *must* be running in order for the framerate limiter to function. So be sure to start the program every time before you play ns2. The program can be minimized to your tray with no problems.9. Play NS2 smoothly and stutter-free again!This made NS2 playable for me for the first time since launch, so I hope this helps others that are experiencing the same issue! Cheers!Also: a huge "Thank you!" to Avengersoul for pointing out the consistencies with frame limiting and the stutter that helped lead me to this fix!
