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).
