I've ended up here because I am having this problem as well. I've tried everything in this thread and nothing works. It's essentially unplayable because I can't look at the screen if it's displaying water! So disappointing.

Is anyone else still having this problem? Has anyone found any other fixes? I'm playing in Windows 8.

Luckily PR 1 seems to be fine, so I guess I'll just stick to that for now :P

I had the same thing happen, I think its because of the shader if you are not running a machine with a dedicated graphics card. Anyways just upgraded to windows 10 and the problem is resolved.

I just found a possible fix on the Steam's forum so I thought I should share it here too.

Many people said to change the settings with the PR2Config tool but the problem I had is that it wasn't saving them. Apparently that could be caused by having the folder set on read only mode. I managed to fix it by unchecking Read Only mode in PR2's root folder and applying to all files and subfolders and running the config tool again. Hope it helps :)

Hi!

My solution for WIN10: Win8 compatibility and everything is checked in the setup except the last point.

Same problem. When I boot the game, water looks like this - imgur.com/a/TxXC8 (end those ugly little rectangles move fast and erratically).

In the last hour or so I've read all of the threads on Steam and GOG that I could find, and I tried different combinations of:
- PRConfig settings
- Compatibility, admin mode, scaling and other executable settings
- Switching between NVidia and integrated Intel videocards explicitly
- Killing explorer.exe before launching the game

The problem persists. Not sure what else I can try, aside from creating a WinXP virtual machine.

I'm running Windows 10 x64 on an MSI GT702PE laptop, some stuff from DxDiag if it matters:

Operating System: Windows 10 Home Single Language 64-bit (10.0, Build 10586) (10586.th2_release.160802-1857)

Apparently all I needed was extra 15 minutes of fiddling. Here's my setup, which makes water look perfect:
- In PRConfig disable full screen.
- Open PR2.exe properties, on compatibility tab click 'change settings for all users'. This one appears to be important - changing settings for your user only didn't have any effect.
- Select Windows XP (SP2) compatibility and check the 'Run as administrator' box.
- Verify that you now have these two options greyed out, make sure everything else is unchecked.
- Enjoy.


EDIT: I was so happy to get this working that I forgot to edit my previous post instead of posting a new one. Oh well.

ok, I will check it out, thanks!

Aaaand it worked!
Thanks a lot for the help!

Thank you! It worked for me as well.
