Performance is lower than expected during gameplay. 4080 using Ryzen 9 5900X
Perhaps around a year ago I upgraded to the 4080, yet its performance didn’t noticeably improve over my 2070 super. I didn’t give it much thought. Recently, while watching an R6 benchmark on the same setup, the video ran smoothly at consistently high frame rates—well above 400 fps—while my own struggled to exceed 240 fps. Both were displayed in 1080p. I’ve tried various fixes, checked all in-game settings and versions, and don’t think it’s a game issue. The game also runs in high performance mode; system temperatures remain stable when I check the task manager. I ran DDU to rule out driver conflicts. It’s not just about R6, as other titles lag behind, but R6 is my primary concern. ReBar doesn’t turn on even after enabling it in the BIOS.
PC specs: Ryzen 9 5900X, NVIDIA RTX 4080, Corsair Vengeance RGB PRO DDR4 3200, C16 2x16GB, Samsung 970 Evo Plus NVMe PCIe M.2 500GB, EVGA 80 Plus Gold, 750W.
This is my first post—apologies if I made any mistakes.
For 1080p gaming, noticeable improvements are rare unless the titles are extremely demanding on your GPU. Rainbow 6 isn’t one of those—especially when you lower the settings to boost the frame rate. It seems your 5900X was likely the main limitation in most runs of the 2070 Super. If you’re into Alan Wake 2, Cyberpunk 2077, or the new Indiana Jones title with high settings, you’ll see a clear performance boost. However, competitive shooters at 1080p won’t benefit much. For top framerates in Rainbow 6, consider upgrading to a platform like the Ryzen 7 9800X3D instead of just a better GPU.
The variation in FPS across your tests likely stems from factors beyond just GPU and CPU specs, such as software settings, background processes, or system load.
It wasn’t the same setting or location in the game. If it differed, it’s clearly not a direct comparison. Some sections will be tougher than others. Overall, historically reviewers reported over 400 FPS for the 5900X on the R6S launch, suggesting the game has improved significantly since then. It’s unlikely the 5900X can consistently hit 240 FPS now, so you’re either struggling to keep it steady or it drops occasionally.
I follow the same graphics options as most comparisons, though the videos show the game as an older release. Other titles still struggle with low FPS, making R6 stand out as the best option. My reference point is the 5900x, which I believe performs better than it appears. I should have done more research before purchasing, but here we are. I find it challenging to maintain an average above 240; it often drops into the 100s, which is my main concern. The benchmark in-game shows 370 FPS, but that doesn’t match my real-world experience. Additionally, streaming puts a strain on my PC—Discord or Twitch both cause noticeable lag, making games feel sluggish. I use a clipping tool, but adjusting it only makes a small difference, so it’s unlikely the problem lies there.
It seems your CPU is struggling under load. You can see GPU usage in games around 65%. Upgrading to a 5800X3D might boost performance by about 20%, or you could switch to an AM5 chip with a 7800X3D for a more complete fix.
Run a 3DMark test or another synthetic test and see how your result stacks against the average.
