XSX虚幻5演示参数公布，1080p~1440p动态分辨率@30帧，1亿多边形

想起了当年ps2的7500万多边形的宣发，直接搞死了DC

所以正式投入大作前，估计PC市场，主机市场又会有一番大升级

100000000 个多边形 比ps2 强了不少啊

minimal

还是要看实机游戏的效果

只有一小段几十秒几乎静态的DEMO，其他全是文字解说，比去年PS5那段寓教于乐高速DEMO差远了

在X盒子區某阿X斯表示這段演示比當初PS5的演示有意義多了

不懂，我还是等荒野大镖客3再决定买哪台吧

说当时PS2虚假宣传可能是过了，但确实有一定程度的误导。

PlayStation 2
Compared to the rival PlayStation 2, the Dreamcast is more effective at textures, anti-aliasing, and image quality, while the PS2 is more effective at polygon geometry, physics, particles, and lighting. The PS2 has a more powerful CPU geometry engine, higher translucent fillrate, and more main RAM (32 MB, compared to Dreamcast's 16 MB), while the DC has more VRAM (8 MB, compared to PS2's 4 MB), higher opaque fillrate, and more GPU hardware features, with CLX2 capabilities like tiled rendering, super-sample anti-aliasing, Dot3 normal mapping, order-independent transparency, and texture compression, which the PS2's GPU lacks.

With larger VRAM and tiled rendering, the DC can render a larger framebuffer at higher native resolution (with an on-chip Z-buffer), and with texture compression, it can compress around 20–60 MB of texture data in its VRAM. Because the PS2 has only 4 MB VRAM, it relies on the main RAM to store textures. While the PS2's CPU–GPU transmission bus for transferring polygons and textures is 50% faster than the Dreamcast's CPU–GPU transmission bus, the DC has textures loaded directly to VRAM (freeing up the CPU–GPU transmission bus for polygons) and texture compression gives it higher effective texture bandwidth.

Dreamcast games were effectively using 20–30 MB of texture data[1] (compressed to around 5–6 MB),[10] while PS2 games up until 2003 peaked at 5.5 MB of texture data (average 1.5 MB). PS2 games up until 2003 rendered up to 7.5 million polygons/sec (145,000 polygons per scene), with most rendering 2–5 million polygons/sec (average 52,000 polygons per scene);[11] in comparison, Dreamcast game engines rendered up to 5 million polygons/sec (160,000 polygons per scene),[4] with most games rendering 2–4 million polygons/sec (average 50,000 polygons per scene).

The Dreamcast is more user-friendly for developers, making it easier to develop for, while the PS2 is more diffi** to develop for; this is the reverse of the 32-bit era, when the PlayStation was more user-friendly, and the Saturn more diffi**, for developers.

PS2?那不是晨风王国那个世纪了吗？玩家还在拿着三流杂志擦屁屁的时代，电话线上网都困难。确实容易被骗。真的我买了NGC玩了rebio我就感觉被7500骗了。现在网络这么发达，人家又不是没有眼睛
