The part about the glass being half empty or half full explains it well and it makes sense when you compare with AMD cards. Take the R9 290X / 290 cards, the drivers came from behind but have been optimized up to this day. Nvidia not optimizing for Kepler at one point in time and thus not extracting the potential that is there in the hardware for new games can be construed as gimping versus optimizing for the new cards. Gimping isn't only deliberately making older games perform worse or new games perform worse even without optimization. It thus all depends on how you look at it, it's also leaving cards behind despite the potential being there. The hardware only performs as well under a higher level API as the driver is optimized to do. You can have all the hardware in the world and not be using it to its full potential. We could of course then proceed to ask whether Kepler would have in certain scenarios any optimization room left vs a comparable AMD card from the same era, that's also an eventual factor, but of course Nvidia won't go there.
A lot of these discussions go around all of the above, both for Nvidia and AMD.
since you're late replying it looks like i need to refresh your memory of the discussion; which was your claim nvidia admitted to gimping kepler via driver release notes
. not about comparing them to AMD drivers - which is entirely another can of worms and imo as irrelevant was comparing clock speeds between them.
i recalled nvidia found a bug effecting TW3 and posted it in the driver feedback thread in their forum. though i looked around and didn't find that specific post i did run accross their statement here
Kepler Performance Optimizations
Following end user reports of lower-than-expected performance in The Witcher 3: Wild Hunt when using GeForce GTX 600 and 700 Series Kepler GPUs, we have identified and fixed three bugs that were limiting performance not only in The Witcher 3, but also Far Cry 4 and Project Cars. With the new GeForce Game Ready drivers installed, frame rates are increased in each title, improving and optimizing your experience.
We would like to thank the community for their feedback on this issue. These reports and benchmarks helped greatly in rapidly identifying and resolving the issue. If you have any further feedback following the installation of the new driver, please post it in this thread.
so though it didn't make it to the driver download page or in the release notes PDF; it along with two other bugs i failed to mention (my bad) IT DID make it on a more in depth driver explanation page.
so there is no smoking gun. and to be clear; my comment about the glass being half empty pertained to the bugs being missed in the first place; nothing about leaving performance on the table - which there is absolutely NO PROOF OF!
have a good day. Edited by looniam - 6/5/16 at 11:56am
