| curl-6 said: Yeah, I was wondering what the go was there. With so many PS2 games (including GT4 itself) failing to hit even true 480p, 1080i seemed a bridge too far. For years people keep bringing up GT4's supposed 1080i resolution to try to make PS2 look better compared to Gamecube and Wii, but it always felt fishy. |
Because people don't make the distinction between rendered resolution and output resolution.

FP16 (Half Precision) gives you better performance on nVidia's Tegra due to Packed Math. (I.E. Two FP16 operations are done on a FP32 unit.)
The caveat is a graphics quality hit. I have already been over this and demonstrated the difference betweem FP16 and FP32 in regards to image quality, so would rather not reiterate upon that again... But the difference can be massive.
The other bonus to using FP16 is battery life, FP16 rules the mobile world because of it, whilst more PC-centric platforms tend to use FP32 exclusively.
FP8 or Quarter-Precision seems to be gaining traction as well, interesting to see how that plays out in the future, should offer double the performance of FP16 if it's packed properly.
What will games use? Well. For tasks that don't need precision, FP16. For tasks that do. FP32. So there will be a mixed use.
Also depends on the developer and their vision as well.
| JRPGfan said: It depends on the programming, if you program everything in FP16..... the code will run just was well as a 1 teraflop FP32 machine. The problem is often they cant get by with FP16, so almost everything is just FP32. The PS4pro can do FP16, and its not really done much for it, it doesnt run like a 8 teraflop machine, compaired to the normal PS4 of 1,84. The same will probably be true for the switch, so for all intense and purposes it ll probably run like a FP32 0.5 Teraflop machine. |
Like hell it does.
You need to understand how flops, regardless of precision relates to how a game is rendered to make such claims.
