Highly recommend installing FusionFix, adds AA, allows to tweak motion-blur & DoF settings and many more fixes to the historically terrible game port. "Fixing GTA IV with 4 Mods" by TJGM on Youtube goes in depth on the benefits and install guide, just requires this launch option for it to work on the Deck, " WINEDLLOVERRIDES="dinput8=n,b" %command% ". A small visual comparison between modded and default: https://imgsli.com/MzU4OTE3 I prefer the look of FSR especially with SMAA enabled over upscaling to 1920x1200, slightly better performance and better battery life, but it's also personal preference. Loading screens on a Sandisk Extreme Pro are the same speed as on the stock 512gb SSD, ~15seconds to get in to game after launching. Power Draw bounces around 15-19.5W depending on Area, and crossing the big bridges usually gives ~30ms frametime spikes no matter the graphical settings, but other than that it's perfectly playable and imo is the Superior Vanilla experience.

I used the auto config in graphics settings with 1280x800 resolution at 16:10 aspect ratio. Increasing the draw distance or shadow quality doesn't seem to affect the power draw much, but I still left them whatever the auto config gave to me.
