For example, something like opaque shadow map rendering doesn't even use a pixel shader, it's entirely done by vertex shaders and the rasterization hardware - so graphics aren't using most of the 1.8 teraflops of ALU available in the CUs. Times like that during the game frame are an opportunity to say, 'Okay, all that compute you wanted to do, turn it up to 11 now.'” [Mark Cerny](https://sms4smile.com/quotes/author/mark-cerny/) ## About This Quote This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation. Unused GPU capacity during rendering can be repurposed for extra visual effects, boosting performance when needed. **In simple terms:** Idle graphics power can be used for extra effects. Key Takeaway Leverage spare compute for enhancements. Themes performance efficiency graphics resource management optimization Mood technical analytical optimistic Type technical educational strategic When to use this quote - game engine design - dynamic scaling - visual effects pipelines - hardware profiling Key Concepts computer architecture real‑time rendering parallel processing Questions to Reflect On - When is it safe to increase compute? - How to balance quality and resource use? A Different Perspective Extra load may cause thermal or power issues. ★ ★ ★ ★ ★ No ratings yet [Available](https://sms4smile.com/quotes/about/available/) [Computers](https://sms4smile.com/quotes/about/computers/) [Done](https://sms4smile.com/quotes/about/done/) [Example](https://sms4smile.com/quotes/about/example/) [Games](https://sms4smile.com/quotes/about/games/) [Gpu Available](https://sms4smile.com/quotes/about/gpu-available-4745664/) [Hardware](https://sms4smile.com/quotes/about/hardware/) [Hardware Graphics](https://sms4smile.com/quotes/about/hardware-graphics-4745662/) [Ifs](https://sms4smile.com/quotes/about/ifs/) [Instant](https://sms4smile.com/quotes/about/instant/) [Looks](https://sms4smile.com/quotes/about/looks/) [Maps](https://sms4smile.com/quotes/about/maps/) [Okay](https://sms4smile.com/quotes/about/okay/) [Opaque](https://sms4smile.com/quotes/about/opaque/) [Opportunity](https://sms4smile.com/quotes/about/opportunity/) [Pixel Shader](https://sms4smile.com/quotes/about/pixel-shader-4745663/) [Pixels](https://sms4smile.com/quotes/about/pixels/) [Portion Gpu](https://sms4smile.com/quotes/about/portion-gpu-4745660/) [Portions](https://sms4smile.com/quotes/about/portions/) [Rendering](https://sms4smile.com/quotes/about/rendering/) [Shadow](https://sms4smile.com/quotes/about/shadow/) [Turns](https://sms4smile.com/quotes/about/turns/) [Use](https://sms4smile.com/quotes/about/use/) [Vary](https://sms4smile.com/quotes/about/vary/) [Vertex Shaders](https://sms4smile.com/quotes/about/vertex-shaders-4745661/) [Wanted](https://sms4smile.com/quotes/about/wanted/) ## Related quotes > [We discovered a person in Lagos who had a fish stall, and within a single square metre she carried two children all the way…](https://sms4smile.com/quotes/rem-koolhaas/we-discovered-a-person-in-lagos-who-had-a-fish-stall-and-within-a/) [Rem Koolhaas](https://sms4smile.com/quotes/author/rem-koolhaas/) > [I always get sick of these conversations where people are so obsessed with pixels, with high definition, and even with technology in general.
