Tested

• Title: Hot Shots Golf 2 (Everybody's Golf 2), PPSA06699, 01.000.004 (PS1 Classic)
• Host: Windows 11, Ryzen 5 5600XT, RTX 4070 SUPER. Relinked with --windows, WinLibs GCC 15.2.0 r7.
• Last update: 2026-10-11 (main a11c8f7)

Status

In game, playable. Menus run at 60 FPS. The 3D course runs at about 60 FPS with the open performance drafts listed below applied; on plain main it dips to roughly 45-49 FPS in heavy scenes. The title draws one primitive per draw call (300 to 1000+ draws a frame), so per-draw driver cost is the limit.

Video below: the attract demo, then me playing a hole.

The 60 FPS result relies on these open PRs by other contributors, none merged yet (several conflict with current main, so I tested rebased copies locally):

PR	What it does	Effect on this title (130 s demo loop, avg FPS / frame drops / min FPS)
#1201	Pipeline queue-0 draw commits behind the packet worker	Off 55.7 FPS, 13 drops, min 21-26; on 59.4 FPS, 4-5 drops, min 50-51
#1202	Cheaper draw commits; pipelined draws on by default	Follow-up to the above; in the combined build, no separate number
#1191	Linear color targets in registered guest memory get a resident image	Off 58.6 FPS, 7-8 drops, min 41 (on top of pipelined draws)
#1193	Cheaper shader-memory captures per draw	In the combined 60 FPS build; no separate number
#1298, #1341	Shader memo and reusable SRT expression plans	Not measured separately

Also related: #494 (draws differing only in user data reuse their decode), #1747 and #1896 (pipelined dispatch and indirect draws). I haven't measured those on this title. Numbers are two runs each on the Windows host above, and the per-PR comments are on the PRs themselves.

Open blockers

Stock 60 FPS in heavy scenes depends on the pipelined draws drafts above being merged.
