After 1.08 The Witcher 3 has become unplayable on my computer! The game runs great, but I'm getting hit with freeze ups constantly, that last up to 10 seconds, and it is really destroying the game.

What happened? Before the latest patches this game ran without a problem..

E8400 3GHZ
Radeon HD 7800
8GB RAM

Sounds like you might be running out of VRAM. Have you tried dialing down the graphics settings a little bit?

Yes, tried lowering it to the lowest setting, and I still get the freezes. And it did function without any problem before the patches :/

Have you tried if the newest patch (1.08.2) will fix your problem? Your graphic driver is up-to-date? Did you change something on your PC or did the problem comes with patch 1.08 as you said before?

Yes, I also went from Windows 10 technical preview to Windows 10 RTM. And I as I installed RTM my graphic card got updated with the newest drivers from AMD. Also tried reverting to the old drivers and back, but no luck.. I have not tried the 1.08.2 patch yet.

Just tried 1.08.2 no change...

Are you sure you are using the latest driver? I don't know if it is the same for AMD but the Nvidea driver you got from Windows 10 upgrade was not the latest and was a bit buggy. Just look on the AMD website for it.

Try this. Find this file in you witcher 3 installation directory, gc.ini, with notepad

Mine is in C:\GOG Games\The Witcher 3 Wild Hunt\bin\config\base

Find this entry, ObjectMemoryTrigger = 290, then change the value to ObjectMemoryTrigger = 512 or 432. 'm using the 432.

I forgot the site where I found this solution. But according to the site, that entry in that file is what triggers the memory to unload the junk files that's in the memory that's no longer needed in the game. when it happens to often, that's when the jitters occur. The default value was too low according to the site, changing it to "512" prevent's the triggering from happening too often too soon.

I am surprised you could even run Witcher 3 on low before the patch with an E8400. I had the same CPU years ago and it is much too weak for modern games. It is way below the minimum requirements for Witcher 3. And it seriously bottlenecks even a 7800.

That, actually seemed to help a little! I still get freezes but now they are shorter and a lot farther apart. Thanks! I could easily run it on high/medium settings before the patch, and still can except I get the freezes. I played the new Batman games, and a lot of other new titles without a problem. My guess is that games are not that CPU intensive, they mostly run on the GPU.

I tired playing around some with the different settings in those files, and got some improvements, so thank you! I will try installing another copy of the Witcher 3 updating it to 1.05 and see what settings they might have changed. Yes, I did try reverting back to my old drivers, and then installed the newest drivers from AMD's official site.

So its confirmed something happened between 1.05-1.08 that destroyed the game for me. The version 1.05 I installed run perfectly without any freezes what so ever.

i hear you. I think so myself, something's wrong with 1.08. The combat is not right. My Geralt sometimes don't move and just stand there like there's no combat going on when I'm giving combat input then suddenly the enemy will drop dead. sometimes in combat the sword will just pass through the enemy like thy're not even there and not getting damaged, yet they can attack me and I take damages. I also get freezes from cut scene. The diagram, formula, and map i purchased merchants, smithies, alchemist/herbalist. won't show up in my inventory, then appears sometime later on. The controls don't seem as responsive as it used to be. I may have to reinstall this game and just patch it with 1.07. I still have all the original installer and previous patches.

My system well within the recommended, not just minimum system requirement:

i5-4460
8 GB RAM
GTX 980

Tried 1.06 and 1.07. And 1.06 also work perfectly, but the freezes came with 1.07.
The weird thing is that the graphic settings does not seem to matter at all. If I play with my normal graphic setting (medium/high), or if I set everything to low, the freezes stil occur.
Really annoying that CD-RED does not adress this!

I have two identically built machines here. One never had problems, the other crashed every 10 to 20 minutes in W3.
Tried a lot of things.
What helped a bit was using msi afterburner to underclock the graphics card. Lowered GPU and VRAM frequency.
The problem is not completely gone... but doesn't freeze more than once per hour (sometimes not even after three hours).
It's not temperature or voltage related, i monitored that.
