New Vegas Parrallels 17 Windows 10 ARM Stuttering/Freezing

I was considering purchasing Parallels 17 for gaming, but I wanted to see if Fallout New Vegas was playable first. It's not. The game loops between the last two frames when you look at certain areas. The game doesn't crash, as soon as I look away it continues running like nothing happened. Unfortunately I've encountered this bug three times in the past two hours of gameplay and I am no longer interested in using the current build of Parallels for gaming on my M1 Mac. If this issue gets resolved I will purchase a Parallels license, but I've seen people posting about this bug since December of 2020 so I don't have high hopes.

 

i have a few issues with games myself but i'm not sure anyone has any way to get around them. My main issue is lighting within games showing lights as free or blue. It's putting me off buying a full licence for parallels because i only need it for gaming and everything else i do on my mac. I suppose it just proves that windows is always the best operating system for gaming.

 

Same here. I really really wanted to play this game in my M1 Mac. I had big hopes with Parallels. But the game stutters afer the first 15-20 min of play and becomes unplayable. No matter if you try window mode, install some stutter remover mod or any other change of settings. I was checking in several forums but it seems insolvable right now. I hope it will be solved one day and I will purchase my parallels license in a heartbeat

 

I figured out how to fix it

 

Gracias Gabboman. I have read in some sites that this is only a temporary solution and eventually you come across the same problem again. Did you do more testing?
Here's the video in YouTube where in the comments all of us all getting the same problem.

 

Hey guys. Gabboman and I have worked on this for the past days and we have finally found the exact issue. It's some water reflections. We also found a permanent fix. You need to navigate to your Fallout.ini and search for "water". Then, you need to change the value of bUseWaterShader from 1 to 0 and safe the change. You may run into some minor graphical bugs when looking at certain types of water, but your game will run smoothly from now on.

 

Just wanted to add here that I have the same problem and thank @JeffAvocado for the fix. Would be great to hear from Parallels developers if any fix can be done, as disabling the water shader is just a temporary fix to avoid the root cause of the problem (and a similar problem seems to affect other games as seen on https://forum.parallels.com/threads/parallels-17-bugs-in-fallout-new-vegas-dark-souls.354346/).
