I've been happily playing the game through Velen, with the graphics settings on moderately-high levels. Occasional 3-4 second freezes, but only a couple of times an hour, with the game running smoothly in between. This is on an Intel Core 2 Duo E7400 - so below minimum spec, and I was completely happy with that level of performance.

Since moving to Novigrad, the game has become completely unplayable. I've turned every graphics setting down to it's minimum setting, 30 FPS, and it's still chunky and unresponsive, with the 3-4 second freezes happening about once a minute. I read the posts in these forums abut dual core machines freezing, and followed their advice by installing BES and limiting the CPU of the witcher3.exe process - this makes the regular play considerably chunkier and worse, without stopping the freezes.

Does anyone have any additional advice on things to try with a sub-par machine to get it running again? I'd really love to be able to finish the game, but it's just impossible in the current state...

Thanks for any help,

Is it sure that it's cause by the processor or are there other parts which are below minimum.
If it's only the CPU there won't be any other solution than getting a better one, the freezes happen when the CPUs cache is full, limiting the processors speed can only help if the arrays are small enough so they can be deallocated before the cache it filled meaning the most neccessary processes aren't too calculation-heavy.
Limiting it means that fewer processes are worked on at the same time but if the most important ones are already too much it obviously cant work.

One idea that might help,check and see what is running in the background and turn off what is not needed.
Try running something that monitors and logs CPU usage, then see where it's at. If both cores are at 100%, time to upgrade.

I remember when Black Ops 2 came out (pretty sure it was BO2) and I was still running my Athlon II x2 250 with a heavy OC and that little chip did it all, until BO2. Performance suffered, game wasn't smooth, etc. Checked CPU usage and it was idling at like 97% per core. Upgraded to the FX 8350 and game played great. I remember being fairly surprised as it wasn't until I got online with the game that issues developed.

There are plenty of decent chips out there now that don't cost a whole lot. Can even go used if need be, though I'd suggest adding fresh paste to te chip.

CDPRed did something in patch 1.08 and since then systems with Core2Duo processors (like mine E8400) have problem with the game. I'm using BES and it solves this problem:

I seem to have found a combination that works for me, with a bit more experimentation. For what it's worth, if anyone else is having similar problems, this is what worked for me:

The _combination_ of running BES, and limiting the witcher2.exe process to -3% CPU, and running witcher 3 directly from the exe, bypassing GOGGalaxy. Neither one worked alone, but both together seems to do the trick. Even lets me run back on medium graphics settings (haven't tried going back to high yet, but medium is still pretty.)

EDIT: Also appears to have something to do with the sound drivers? I have a set of USB headphones, that use a different driver than my normal sound. Game works fine through the headphones (with the fixes above) but stutters horribly off the normal driver (fixes or no.) So anyone having similar problem might want to try experimenting with different sound.

Thanks for the advice folks.
