List of CPU speed sensitive games
From Vogons Wiki
This is a list of games that do not run properly in some ways on CPUs faster than what was common than at the game's release. 1990+ for the most part, since before that, this was more often the case than not: As a general rule, games for IBM XT computers require a 8088 4.77 MHz to play right.
Some CPUs, for example AMD K6-2 and earlier Pentium IIs have selectable multipliers, which may help with achieving the lower speeds recommended for some of the games in this article. Additionally, disabling L1/L2 caches will slow down the processor as well, e.g. a Pentium III with disabled caches will be comparable to a 386. Also, it is possible to use a slow 3D card to slow some of the games down, especially with the early proprietary APIs; a special case here are Rendition Vérité cards, since their slow VGA performance will also bottleneck DOS games using these modes.
For games with unlisted optimal CPU specs refer to the minimum requirements published by the developers.
