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. Setmul is a software utility by forum member gerwin that allows multipliers and caches to be changed/disabled and enabled without a reboot. For certain P54C Pentiums, it also allows manipulating Test Register options for further speed control.
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. Finally, as a last resort one may try slowdown utilities such as CPU Killer and Mo'Slo.
For games with unlisted CPU specs refer to the requirements published by the developers.
