When framerates start to drop, the modern reflex is to open the graphics menu and toggle DLSS. It works and there is no problem to use it. But first, reaching it means accepting a reconstructed image before checking if the missing frames are in the settings menu all the time. Most players run whatever presets the game automatically detects at startup, and “ultra” presets have a habit of spending a disproportionate amount of the frame budget on the final quality of a few specific effects, so it’s really hard to notice once the scene is in motion. Here are the seven parameters below performance budget tends to hide.
Shadow quality
The overlooked performance killer
Shadows are consistently among the most expensive settings in the modern game, and the highest quality tier is usually the worst offender in terms of cost versus benefit. Effectively rendering dynamic shadows means capturing the scene a second time from the light point of view to create a shadow map, so higher shadow resolution and longer shadow draw distance add real work to each frame.
Shadow drops from ultra to above typically recover in the ten to fifteen percent range, and in a few heavy open-world titles, the ultra-medium jump measures higher still. The visual trade-off is subtle in practice: the shadow edges are somewhat soft, and the shorter distance before the shadows fade is rarely noticeable to the player as they progress through a level. This is the first setting to drop.
Volumetric lighting, fog and ray tracing
These three are put together
Volume effects such as god rays, volume fog, and volume clouds are often as demanding as shadows, as they sample how light is scattered across the air volume per pixel and scale hard with resolution. The payoff is atmosphere, but the performance hit can be really hard, especially for something a little situational.
A heavier relative of this family is ray-traced global lighting, which some recent titles have featured as a lighting option. Real-time GI is one of the most transformative settings for scene realism, and also one of the most expensive in the entire menu, with ray tracing widely capable of reducing frame rates by a third or more. For a player chasing frames without an upscaler, the ray-tracing lighting switch is usually the single biggest lever available, and in most games released in the last few years, the rasterized return looks closer to the ray-traced version than the performance gap would suggest.
Environmental congestion
A type of shadow that has a noticeable impact on visuals and performance
Ambient occlusion adds soft contact shadows where surfaces meet, and its value is very method dependent. Screen space implementations like SSAO are relatively cheap and worth keeping, more advanced options like HBAO+ or GTAO cost more, and ray-traced AO is particularly demanding.
The truth is that the difference between mid and high levels of AO is often hard to see in normal play, so taking it down a notch is a less regrettable change. If the game specifically offers a ray-traced AO option, you should avoid it if the performance is poor.
Reflexes
If you can handle the quality drop, it’s worth enabling the button
Reflections are where a little more attention is needed, as they are more noticeable than most of the effects on this list. At the highest settings, screen-to-body reflections are average, and ray-traced reflections are a notable frame grabber. A reasonable step is to lower the reflection quality by one step instead of turning it off and treat the ray-traced reflections as an extra layer to provide only empty space. It’s visually the setting where a certain player is most justified in protecting, so it’s listed as a considered trade rather than an automatic cut.
Anti-aliasing
Last line of defense before upgrade
Anti-aliasing is a last line of defense worth playing with before upgrading in a VRAM-constrained scenario. If the header offers MSAA, switching to a temporal method can recover a large stack of frames, since MSAA increases sampling costs, while temporal anti-aliasing works less expensively. The caveat is that MSAA is mostly left out of modern games built on deferred renderers, where it breaks with the pipeline, so this mostly applies to older or simpler titles that are still listed.
TAA isn’t free either and doesn’t look great in my opinion. Your mileage may vary, and if playing with this setting doesn’t affect you much in your particular title, upscaling may be the answer, as pure anti-aliasing is baked into DLSS and FSR anyway.
It’s worth a quick trial and error check
The bottom of the menu is worth a quick look. Rendering motion blur, chromatic aberration, and film grain is cheap and mostly a matter of taste, so turning them off isn’t a meaningful performance game, unfortunately for many gamers who don’t like them anyway. Depth of field and high-quality blooming sit in a different category, as they can cost real frame time depending on the implementation. Grouping these into one pass at the end grabs a few easy frames and cleans up the image at the same time.
Texture quality
If you are limited in VRAM, this is where you go
Most people instinctively feel that low settings are often the case they shouldn’t touch. Texture quality is mostly related to video memory rather than raw GPU calculations, which means that on a card with enough VRAM, high or even ultra textures often cost next to nothing in frames, remaining the single most visible detail in the game. Downgrading them in pursuit of performance usually sacrifices the most obvious visual improvement available to frames that were never really worth the cost.
An important exception is when VRAM is already saturated: at this point, it is a setting that will save system performance, causing stuttering and crashing one percent minimums, as the system switches assets to slower system memory, and this may not always happen during a gaming session.
DLSS is great, but there are other settings worth tweaking
The goal is not to swear off DLSS forever, quite the opposite restore frames in other ways before the “performance” upscaling preset. Improvement It remains the single most effective way to recover frames, and stacking it on top of a well-tuned settings profile is a great result, but getting there skips a bunch of free wins in the first place and allows you to accept a reconstructed image while natural clarity may still be on the table.
