Our Creative Director Sam Lake with his Lifetime Achievement Award from the GDCA.

Sam accepted his award last night from Matthew Porretta, the actor for Alan Wake and long-time collaborator with Remedy. "He creates with a giving spirit, he sees people's greatest potential and he guides them to it with ease and enthusiasm", Matthew said about Sam.

As a longtime Max Payne fan and admirer of the @remedygames I created this web-based tribute demoscene (link in the comments). I’d be grateful if you could check it out, any feedback or a repost would be greatly appreciated. Thank you!

Clay by @nicbarkeragain https://t.co/tjAClkBp2l looks like an excellent library. I will give this a spin during my time off and see if I can use it and save my time instead of implementing my own similar thing :)

[Eric Lengyel @EricLengyel]

I get a lot of emails asking about one-person licenses for the Slug Library. Information about that is now available on the website at https://t.co/wS0gJL7Isa, and it's copied below. Feel free to contact me with additional questions or to get yourself set up!

We have a single-engineer license for a one-time cost of $1500 (USD). This license includes the full source code for the Slug Library and associated tools, it allows usage in an unlimited number of commercial products, and it includes all future updates at no additional cost as long as you’re solo.

The Alan Wake 2 expansions art blast is out now on @ArtStationHQ

Take a glimpse behind the scenes of our process: https://t.co/tCCVGPFP5L

The expansions provided the Alan Wake 2 team with the opportunity to experiment and broaden their palette of horrors. #AlanWake2

[Fabian Giesen @rygorous]

We just released Oodle 2.9.13.

Significantly increased BC7 encoding speed (about 20-25% encode time reduction for non-RDO on typical content, 25-30% encode time reduction for RDO) at slightly increased quality.

Also several bug fixes and experimental WASM 64-bit support.

@rovarma @molecularmusing @mikulasflorek @SuperluminalSft Extremely funny, am so curious what in the picture tripped it up

[Jack Knobel @jack_knobel]

What’s the fast way to query if a file exists on windows these days?

Still GetFileAttributesEx?

[Jack Knobel @jack_knobel]

@molecularmusing @mikulasflorek @SuperluminalSft Pictures in both are of the maximum call

*Should* have exclusions applied for AV

Pic one makes a bit of sense where writing to the cache has to wait but ideally I could just skip the cache for this part and hit the cache later when I read in bulk
