...it would be cool if RealMystMasterpieceEdition would be patched to a level with good performance. Seriously, this is performing so crappy. Looks like you should upgrade to a more recent version of unity ASAP. Because right now, ingame-Maxed Witcher III runs better than this one maxed. That´s very unefficent!

I'm running it in 4K at 60 fps.Upgrade? ;)

Yes, Unity is not the most efficient engine.Still, it should be possible to update a PC every few years. Back in the 90s you had to do it every 2 years because technology changed so fast.

Your guess isn´t that good. ;)

Course on my GTX 1080 I even get framedrops below 60 even when turning down the res to 720p. Yes, there are many areas in which I get 60 FPS@2160p. But then there are also many mid 30-areas low 40-areas with poor GPU utilization. On top of that, the game got hitches. Hitches that even persist in 720p. (they only go away when lowering the details, which isn´t appropriate for a game looking like it does) If I underclock the 7700K, performance drops even further.
→ Most probably poor CPU-optimization in older Unity Version, that´s why I believe switching to UpToDateUnity might help.

On thing that comes to my mind: Are you running a Vega 56/64? Maybe it´s running better on AMD. Not very often the case that AMD performance in CPUlimit is better then Nvidias, but it might be.

And well, as I said, it´s generally bad optimized in a way of beeing unefficient. The game should have either stellar graphics with this performance or stellar performance with these graphics. Right now it got neither for me.

I do hope that this version will continue to be supported with updates. They have patched it occasionally, so I won't be too surprised if they keep at it.

Performance aside, I'd also love to see the mouse-driven free-roam mode from the old RealMyst return as a control option, since that was always a bit more intuitive than WASD controls, and more fluid than classic mode. Would also love to see an option for instant or fade transitions in classic mode, like the ones in Obduction, since the camera movements in classic mode are often erratic, and instantly jumping to the next screen or node would feel more like the old Myst.

Just bought realMyst Masterpice in steam as it was way cheaper than in GOG but after playing the beginning I had to refund it. The game runs like ass as its using Unity 4. I think I will keep original realMyst here in GOG and will only dip in the Masterpiece version if they dedide to port it to Unity 5 or make it run at a proper framerate.

Has the game really become that buggy? I bought it when it first came out in 2014 and while there were bugs, for the most part it ran perfectly fine on my Intel integrated GPU in my laptop. They patched it a few times (and the first 2 really did improve things) but I haven't played it in a few years. Now everyone's saying it runs like crap? I guess I need to replay it for myself.

Honestly, I'm running an 8GB RX-480 and have no trouble with frame rates or stutter--IQ maxed in game settings--running at 2560x1440 (native res for my present monitor.) I mean you'd expect that, really, in a title this old. I will say this, however--what happens when you go to 1440p? Have you tried that, just to see if your GPU is struggling with 4k in this particular game?

Edit 1: Went back and fired up the game just to make sure nothing had changed--no problems--make sure you turn off vsync. On my system it's zippy @ 2560x1440 & max IQ--all graphical effects on. The AMD drivers have a nice feature called Enhanced Sync that you set in the driver control panel for the game while you turn off vsync within the game itself--runs the game at 90% of the vsync-off speed while at the same time it eliminates 90% of the screen tearing usually produced from vsync off--works very well.

What happens for you with vsync off? I know you tried it at 720P but was that with vsync off? Interesting that this would be a challenge for your card & driver, etc.

Yup, tried VSYNC off and 720p. (as well as 1080p, haven´t tried 1440p in particular) Got many scenes with ultra-high framerates, but each time a lot of stuff is on screen it drops below 60. Good benchspot for that: One end of the island. I use the one with the large gear.

Can you try that one? If you get good framerates there as well that would stress the thesis that the game dislikes Geforces. Ah, due to the day-night-cycle-feature of RealMyst the framerates can vary over the day.
BTW FYI: The Geforce-pendent to AMD Enhanced Sync for Radeons is called Nvidia Fast Sync.
