Some report framerate increases of up to 20%.
The Team Fortress 2 Heavy eating a sandwich.

On April 18, 2024, Valve released an update for Team Fortress 2. This alone isn't terribly noteworthy, if only because Valve (well, at least one person at Valve) has been actively updating the competitive team shooter somewhat regularly over the past year. What is notable here is the fact that last night's update added 64-bit support for the 17-year old game.

I had actually completely ignored last night's update when it came across my RSS feeds because the changelog was so short. Though it was indeed quite short, it offers perhaps one of the biggest changes to the game in years.

The addition of 64-bit support for Windows and Linux clients and servers should result in some big performance gains across the board. On average, those that have reported improvements are seeing about a 20% increase to average framerates. Others, while suggesting they haven't seen an improvement in max framerate say that the game feels a lot smoother now, indicating that there are fewer framerate drops compared to the old client.

There were two updates made last night, which can be seen in the combined changelog below. Sadly, while the increased performance has been welcomed by the Team Fortress community, they are still largely upset that the issue with disruptive bots has not yet been addressed.
