It is also commonly used for the creation and publishing of videos on YouTube, mainly from Team Fortress 2, Half-Life 2, Portal and Left 4 Dead.

Garrys Mod

GeForce RTX 2080 Ti

Low Vs Ultra GeForce RTX 2080 Ti Performance Review

Viewing the performance found on the 3 year old GeForce RTX 2080 Ti while playing Garrys Mod we quickly see it can return a consistently high 200+ frame rate. Which is at High settings on 1080p performance.

Playing Garrys Mod on Ultra 4k is certainly possible with this graphics card and we expect it will return around 200+ frames per second at that top scale resolution.

Finding a PC with this gpu or better would return some strong FPS in Garrys Mod. We would definitely recommend running at 4K screen res and on ultra, before trying any lower screen resolution. You would also need at least 1GB of RAM. Perhaps couple this gaming PC with a processor that's as powerful as the Intel Core i7-8700K 6-Core 3.7GHz and Ultra 4K would be a smooth experience.

To summarise, GeForce RTX 2080 Ti graphics cards can smoothly run this game, but what Garrys Mod screen resolution would you like to run with? While you can get 200+ FPS with 4K Ultra you can increase your frame rate to 200+ FPS in Ultra 1440p and up to 200+ FPS with 1080p. Pricing this on a frame per frame around the graphics cards original price it will cost $0.34 per 1080p Ultra frame. This increases to $0.45 per frame at 1440p Ultra and even more with 4K Ultra at $0.76 per frame.
