Lucid Dynamix increases gaming fluidity on notebook IGPs

Computex — Lucid has done all kinds of interesting things in systems with multiple graphics processors. Now, it's targeting notebooks equipped only with Intel integrated graphics. The company's new XLR8 Dynamix software is designed to allow slower GPUs to deliver playable frame rates by, ahem, dynamically lowering the texture detail of background objects. We saw Dynamix demoed at Computex, and it appears to have some promise.

Dynamix was showcased on two systems: a Sandy Bridge notebook with Diablo 3 and an Ivy Bridge system with Battlefield 3. Diablo 3 ran at 18-20 FPS with Dynamix disabled and around 35 FPS with Lucid's new mojo turned on. The improvement wasn't as dramatic in Battlefield 3, which jumped from 15-19 FPS to 21-24 FPS in the short snippet of gameplay we were shown. Background textures looked a little fuzzier in both games, but the improvements in fluidity were more apparent than the degradations in image quality. Unfortunately, we had to run to another meeting and couldn't spend more time with the systems.

According to Lucid CEO Moshe Steiner, Dynamix was inspired by an Intel whitepaper on texture scaling. Dynamic texture scaling is hard to do, Steiner admitted, but he said the company's experience working with rendering objects helped it to develop algorithms that identify background textures that are good candidates for scaling. Those algorithms are still being tuned, and users may be given control over how aggressive they are. We'll know more later this year; Lucid is planning to release Dynamix in the fourth quarter.
