The textures the game lets go of were kept for three minutes and could hold a quarter of the card's budget, up to 8 GiB with room. A run through Hyrule Field shows what that bought and what it cost (RTX 5090, 5120x2160 with DLSS Performance, about three minutes of running; the game keeps 4.8 GiB of textures live and loads about 190 a second): the released textures held 5.3 GiB on average and the video memory in use went from 11.1 to 17.9 GiB, while the game took back 1,494 MiB of them within 10 s of the release, 171 MiB within a minute and 10 MiB later, beside 33,000 textures it loaded anew. A shorter hold alone gives nothing back: with 20 s the released textures fell to 0.5 GiB and the free space inside the allocator's blocks rose to 4.9 GiB, since a block returns to the driver only when it is empty. What the released textures hold at their fullest is what the session costs, so the bound is the lever. The bound is now a thirty-second of the budget, 384 MiB to 1 GiB (vk_tex_release.h trl_cap_mb), still doubled while the card and the commit have room, and the hold 60 s, 120 for content only the GPU made. The same run with the new defaults: 13.2 GiB in use on average against 16.7, 13.8 at most against 17.9, 532 MiB of textures made again over the run, 77 fps against 75. An 8 GiB card keeps 384 MiB where it kept up to 1.9 GiB. tests/tex_release_check checks the bound by the budget and the sessions it simulates against the rule before. Compaction (tex_compact) and 16 MiB blocks were tried on the same run and gave back 0.7 and 1.2 GiB; neither is changed here. Co-Authored-By: Claude Fable 5.2 <noreply@anthropic.com>
