The Elder Scrolls IV: Oblivion Remastered PC Performance Review and Optimisation Guide
Preset Scaling and Lumen Performance
Low to Ultra – Huge performance difference
I’ll say it now, and I’ll say it again, Ultra settings in this game simply aren’t worth it. The performance drop is enormous compared to High, and the visual gains aren’t that noticeable. Again, medium settings can provide much more performance than high, though this comes at a more noticeable graphical cost. Pop-in is more noticeable at medium. That said, the game still looks great.
When it comes to Low, I’ll just say that these settings are a huge drop in image quality. Lighting is changed and pop-in is constant. Image quality is sacrificed in the name of performance, and the changes are massive. Honestly, low settings make me want to play the original Oblivion instead of the remaster. Medium is the minimum viable preset for playing this remaster.
When it comes to this game’s Lumen settings, Software Lumen (SW Lumen) looks great at all settings, even at low. Using hardware-accelerated raytracing for Lumen results in some enhancements, but also results in lowered performance. Since this game is already demanding, it is likely best to keep Luman in software mode and set to low. That said, if you have an ultra-powerful GPU, you can go nuts and max this setting out.
