Left 4 Dead 2 gets RTX Remix ray tracing, tanking performance by 20 times on RTX 5080 in 4K resolution
Translated with AI from the Russian original.
Left 4 Dead 2 still attracts gamers, but some would like to revamp the visuals. However, eye candy comes at the expense of performance.
Recently, thanks to NVIDIA RTX Remix tools, path tracing was implemented in the shooter Left 4 Dead 2. The game is visually transformed, but it is not just the visuals that change drastically.
This mod for Left 4 Dead 2 has very, very serious performance issues at 4K resolution.
The creator of the YouTube channel MxBenchmarkPC tested the mod and showed how on his PC with an Intel Core i7-14700F and Asus RTX 5080, the FPS counter drops from 500–600 down to 20–55 once ray tracing is enabled, depending on the scene. In the tests, he used NVIDIA DLSS 4 in various modes and also turned on Frame Generation.
During a gameplay test of Left 4 Dead 2 at 1440p resolution and DLSS Quality, the situation was noticeably better: the counter stayed around 55–65 FPS. After enabling FG, he managed to reach around 90–100 FPS (1440p).
