Now: One important point to note is that (in my setup at least), anti-aliasing is set to "off" for the DX9 version - the option is grayed-out (the screenshot above is for the graphics settings for the DX11 version). The graphics options available in Civ5 are shown below: Other graphics options, I all set to "high" detail level. This is the standard option, and designed to give a smooth display. Now, I'm no expert, but I understand that this option forces the game to limit the number of frames per second to the screen refresh rate. Resolution was set to 1920x1080, 60Hz refresh rate, and "WaitForVerticalSync" set in the game options. All tests were run on this, using a ViewSonic VX2433wm 24" widescreen. I'm not really sure why it concluded that, but to allow this to be a graphics-focused discussion, I used my more modern PC - a Core i7 860. I ran the "System Requirements" checks using System Requirements Info on my older PC (Core II Duo, E6600 running at 2.4 GHz), and it told me I met the "minimum CPU" requirement, but no the "minimum speed" requirement for the CPU. I have two PCs - one is a few years old, the other not so old. We will also use this as an opportunity to tell you about a NVIDIA Civilization 5 promotion, but we'll get to that later. So I saw this as an opportunity not to review the card per-se, but to show you how such a card can (in my opinion) improve the look of Civilization 5, by giving you access to all the bells & whistles that come with DX11. Well, we're not a hardware review site, and if I tried to get into the technical details of the benefits of CUDA vs other graphics architecture, I would get shot to pieces by those who know a heck of a lot more about it than me. NVIDIA proposed that they could send me one of these cards for review. NVIDIA have been providing some support to Firaxis on the graphics hardware side for Civ5, and just over a week ago, they released a new entry-level (affordable) DX11 card, the GeForce GTS 450. CFC was contacted a couple of weeks ago by NVIDIA. For those of you that have Vista SP2 or Windows 7, but don't have a graphics card that supports DX11, hopefully this article might help you decide whether an upgrade is a good option.īefore we get into the differences between the two, I need to give you the "disclaimer" bit. For those of you who have Windows XP, unfortunately you're out of luck: DX11 is not supported under XP. In order to play the directx 11 version, you need to have both a video card that supports DX11 (ATI Radeon 5XXX or higher, or NVIDIA GeForce 4XX or higher), and an operating system that supports DX11 as well: Windows 7, or Vista (SP2). In this review here, I will endeavor to show you the differences between the two but first a word on availability: There are currently only a handful of titles that have been released with DX11 support, and Civilization 5 is now one of them.Ĭivilization 5 ships with two versions: a DX9 version, and a DX11 version. The first game to be released supporting DX11 was the RTS game BattleForge, initially released as a DX9 / DX10 game, and updated to support DX 11 in September 2009. DX11 adds some new features to allow better graphics details, such as tessellation and improved multi-threading, along with some other graphical enhancements. DirectX 11 (or DX11) is Microsoft's latest incarnation of the DirectX API, a set of Application Programming Interfaces that are used for multimedia on a PC, and graphics in particular.
