Despite saying previously you've ran out with 12Gb:shrugs
Besides, because you don't run out running X settings doesn't equate to vram not running out on Y settings, clearly shown by the multitude of users reporting running out of 8/10/12GB vram, even some 4080 users have reported running out of 16gb vram in here and in Games sub.
Gpu grunt to vram allocation was made irrelevant in 70 and even 80 class gpu's in 2022, vram is the problem requiring turning down textures from max is a must in some titles, Avatar, SWO, Indy, SM2+Texture pack that Iv'e ran on the 4070@1440p-and that's not counting the games you have to restart with performance drop off if your having a heavy session or automatic texture degradation/loading in slower-plenty tech vids have been reporting it for years at this point.
Last year DF eventually jumped on reporting vram deficiencies even on Nv titles-Nv clearly don't care at this point.
16Gb 70ti is likely going to cost upwards of £800-they've successfully vram locked performance tiers because we'll buy anything they throw at us.
