`r_renderWidth`

Vulkan

Needs review. The inventory/provenance evidence is recorded, but some behavior, options, or attribution still lacks a direct user-facing source.

Controls r_renderWidth in the renderer module. Consult the cited behavior reads before relying on values not listed here.

Dated project introductions

Authored dates come from the exact registration’s first content commit, PR dates identify when work was proposed to each project, and integration dates come from each first-parent mainline. A project merging first does not override earlier upstream authorship or submission.

Later changes

These commits occur after the ultimate-origin introduction on TaystJK’s inherited first-parent lineage. Registration evidence is exact; behavior evidence requires a changed bound cvar reference or a changed registered command-handler hunk.

Date	Change source	Commit / subject	Evidence	Confidence
`2021-10-26`	TaystJK	`098a1d69a6c4` Fixed r_renderscale & splash offset	Changed an exact bound cvar-variable reference. `codemp/rd-vulkan/tr_init.cpp`	`medium`
