Cannot Enable TressFX on Nvidia Card Despite the Feature Being Vendor Agnostic

[ltron]

Hello, I bought this game in the steam sale and can't enable TressFX. I have a gtx 690 (still a very powerful card, equivalent to 780ti performance or better) and tressFX works fine in tomb raider and I very much enjoyed it in that game.

I understand you disabled this for Nvidia cards, however I'm not sure why, as it's vendor agnostic and should work fine on Nvidia cards. I understand there is a significant performance hit, but I'd be very grateful if you could tell me if there's any way to enable it so that I can test it for myself?

Many thanks,
ltron

We purposely disabled TressFX on NVIDIA cards. We delivered TressFX on AMD hardware as part of our partnership with AMD.

Thnak you for the reply [Xav] Shohei. However, I'm still unclear as to why you disabled TressFx on Nvidia GPUs. Your statement about your partnership with AMD is contrary to their marketing mantra which is one of open standards and no proprietary software that's locked to their own brand, where feasible. This ideaology is one of the reasons I respect AMD and will probably get an AMD GPU next time, if they deliver.

TressFx is based on the Direct Compute Api which is vendor agnostic. Here is a link to AMD's material on TressFx 2.0 which shows that the performance hit is the same on both AMD and Nvidia cards:http://community.amd.com/community/amd-blogs/amd-gaming/blog/2014/09/23/tressfx-hair-cross-platform-and-v20

This technology is very different to GPU PhysX (locked to Nvidia) or Nvidia Hairworks (ironically, this performs worse on Nvidia cards than TressFX according to AMD).

Good work on the game, I'm enjoying it.

Well theyre foolish Tressfx is disabled in game but just run game once and then go to:

C:\Users\USER\Saved Games\Lichdom Battlemage and edit game CFG file put in there g_UseTressFX=1

save file and close and voila you ahve Tressfx on Nvidia GPU

Please enable it also in Graphics menu why not if you anyways can sue it?

Editing the game.cfg does nothing. Tried it and still no TressFx with my Geforce :(.

TressFX is open and can be implemented on nVidia too. These kind of decisions are frustrating for users.
