AMD Surface Optimizations Setting
« on: January 16, 2016, 09:32:30 AM »
Hey Radeon users,

I have been doing my usual testing & checking performance on my Fury X & have found out that using this setting is actually sapping more GPU cycles than by not using it.

This setting is a holdover from the ATI days as a means to "enhance" texture filtering performance by applying FP11 coding to FP16 coding (layman's terms--to make bilinear texture filtering appear to be as trilinear texture filtering to keep the appearance of trilinear texture filtering being applied in graphics rendered frames (looks sharp) but is actually bilinear texture filtering being applied at specific places in rendered frames.........IOW's a graphical "cheat" by ATI which Nvidia called ATI out on this back in the day.

What I'm seeing is that w/ this Fiji GPU's capabilities this setting is causing the GPU to not optimize itself (slow down) & lower FPS over allowing the GPU to do full FP16 coding of true trilinear texture filtering (texture filtering setting set to High in AMD driver & surface optimizations set to "Off") most likely due to this old code not being really a focus to optimize anymore and IMHO AMD should just remove it from the driver code but I know that there are plenty of older AMD\ATI GPU's still being used to warrant AMD leaving this coding in the driver stack.

You might check this out if you desire.................

Hey Pudgie, are you using the newest AMD Graphics Driver? think it's the Crimson 16.1 Hot Fix driver?

Hi TC,

Yes I was using it for a while but I've since wiped it out & rolled back to Crimson 15.12 WHQL.

When I installed the 16.1 Hotfix driver I tried to install just the drivers themselves w\o reinstalling Radeon Settings.....for a while it appeared that all would be well.........until I noticed that none of my game profiles settings would save anymore....all kept reverting back to the Global settings so I wiped all out, ran DDU & cleaned all remnants & tried a fresh install of Crimson 16.1 Hotfix along w\ Radeon Settings but box kept BSOD upon startup....crash dumps stated issue w\ the video driver. Wiped it again & tried to reinstall again but got the exact same BSOD so I deleted it, ran DDU & cleaned all out again then reinstalled Crimson 15.12 WHQL along w\ Radeon Settings which fixed it all so I'm back to 15.12 for the time being.

Saw the same benefits from 15.12 WHQL drivers as I saw from 16.1 Hotfix drivers...................
