Optoma H33 - Bulb at End of Life - 3D issues

So I purchased and Optoma H33 some 5-7 years ago, I can't remember. None the less the bulb has over 2500 hrs on it, most of the time using the bright setting. As of a few years ago I noticed that my 3D content was almost unwatchable for anything that had any kind of motion.It like anytime anything moves across the screen there is a MASSIVE amount of what I would call judder or motion blur to the point that it's unwatchable. I never remember having this issue in the past, watching something like Avatar. I wonder if it's possible that the bulb dimming has caused this issue. Maybe the bulb being dim, now the "DLP Sync" flash is becoming noticable and distracting during the motion scenes? Or are my eyes just getting old? Also, since I have to buy a new bulb, I was thinking about just getting a new projector, something around 500-700 max, 1080p (I'll wait 5 years for 4k) 3D capabilities and HDR preferably. I was looking at the Optoma HD146X or the HD143X. The only thing I do notice is that they don't have frame interpolation, which my H33 had and was used during 3D playback. How much does not having this option for 3D playback is the smoothness affected? Any recommendations?

It is possible the dim lamp my be causing an issue with the 3D sync if your not using RF glasses. A bare lamp for the HD33 should be well under $100 and is fairly easy to change into your old housing, well worth the try. FI is very rare in DLP projectors and the HD33 was very good at it so a new lamp might put enough life into it for another few years.
