From 2fc491c3898ad429b17a82f8cc108c8fee0f9a80 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?R=C3=A9mi=20Bernon?= Date: Fri, 14 Feb 2020 11:01:39 +0100 Subject: [PATCH] dinput: Increase device buffer size to 1024. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The buffer size was previously limited to 20 in: 8d052561724f9c8d9e7770964bfaebdd01e98e60 Testing shows that it is somewhere around 1024 on Windows, and using a smaller buffer causes some input data to be lost with high polling rate mouses. It can be spotted in Wolfenstein II: New Colossus menus.
