Performance declines when launching two games simultaneously on Steam.
Performance declines when launching two games simultaneously on Steam.
Hello everyone, the games I play together are Dota 2 and Rocket League. I usually let RL run quietly in the background while I play D2. When RL is active, my FPS drops from around 100 to about 50. My setup includes a 4690k Stock MSI gaming PC with 5 Z97 8GB Corsair Vengeance RAM at 1600GHz, an SLOG Swift 144Hz monitor and a 1200p display. While both games are running, CPU and RAM usage are roughly 70%. I’m curious if my hardware is the issue or if the game performance is affected by Steam settings.
You're experiencing FPS drops because you're attempting to play multiple games simultaneously... what were you hoping for?
Avoid playing two games simultaneously... sounds reasonable... your system is okay and Steam is functioning, but the issue is attempting to run several games at once. .-. Even though they require a lot of CPU power...
Ensuring both are fully visible in the window might make a difference. On an i5, playing two games is quite taxing on the CPU even with one GPU. I’d definitely not suggest using SLI on an i5. The 0 thread is being pushed too much.
The simplest approach is clear—play one game to achieve high FPS, then try two for lower per-thread performance.
It mainly relates to an i5 setup. SLI adds a lot of extra processing load, while i7s perform better even when GPU usage is high. X99 demonstrates significant gains over z-series i7s in SLI configurations. A short demo highlights these differences. It's not the most impressive case overall, as many reviewers overlook such concerns; however, Digital Foundry’s work shows clear microstutter reductions when moving to a quad-core i7. Considering that two-GPU setups carry more CPU overhead than single CPUs, these benefits should be expected.
