Valve’s latest client update shifts Steam to 64-bit on Windows systems.

Valve has previously said that 32-bit Windows installations represent around 0.01% of active Steam systems.

I feel like it’s fair to sunset 32-bit Windows support if this segment represents 0.01% of your installed base

If they’re willing to issue refunds for all games bought for 32bit.

Are there any games that won’t work on 64bit?

Portal 2?

Guessing or do you have some edge case to present? Last I tried portal 2 ran fine on 64bit system. In fact I’m not entirely use I have ever actually ran it on 32bit one.

Guessing. To my limited understanding it relies on 32bit OpenGL drivers. Or later they made vulkan support, but that needs to be enabled via custom launch option “-vulkan”

64 bit architecture can emulate / run 32 bit processes but the reverse doesnt work.

They could, actually. I was there, in the olden times.

Not efficiently, of course. And these days it’d be a disaster. But it was possible.

You learn something new everyday, must have been prone to mem allocation issues no?

I had the choice when buying a new PC to go with single threaded 64-bit or multiple cores. Particularly for gamin, I figured a single fire was all I really needed, and 64-bit was the future.

The correct choice at the time was multiple cores. Everything going to 64-bit wasn’t going to happen until that computer was long dead.

All of the 16bit and older games will have to be emulated.

While true… I’m not aware of a single 16-bit game sold by steam. Are there actually any?

Admittedly sample size of 1, but the only 16bit windows game I care about (Castle of the winds) runs fine on wine.
